As far as God's plan goes, God's original plan was for humans to be in the garden of Eden which was paradise with no sin and no suffering. Because of the devil's temptations and human's sinning against God, now we live on Earth with the consequences of sin. God's ultimate plan is to bring us back to paradise in Heaven.
Although God knows everything that has, is, and will happen, and is all powerful, he allows for people to have free will, and there will be suffering in this life.
John 16:33
I have said these things to you, that in me you may have peace. In the world you will have tribulation. But take heart; I have overcome the world.”
For Israel, God's original plan in the Old Testament was for Him to be their king, but they refused to have Him for their king so He eventually listened to their wishes and had a prophet appoint Saul as their king and eventually David. But that wasn't His original plan. You can read about in 1 Samuel 8.
God wants to and is trying to save everyone, you and I included. 2 Peter 3:9. If God liked the devil and was on the devil's side, then God would not throw the devil into the lake of fire at the end of Revelation 20:10. the devil is God's enemy. Just because God has not eternally damned the devil to the lake of fire yet, doesn't mean that they are buddies. Have you heard of the new TV series called Lucifer? I don't recommend watching it. I've watched a couple of episodes, and although it is written well, it asks a lot of twisted questions that are meant to turn people against God. I don't remember any off the top of my head, but they are in there. My point is you aren't the first person to write a story portraying the devil in a positive light, and probably won't be the last. I've read posts on this forum in the past about people that see the devil in a positive light and others that even pray to the devil. I'm not saying that doing that is ok, but that you aren't the only one.
You're asking what God wants of you? There's a passage that talks about that.
Micah 6:8
He has told you, O man, what is good; and
what does the LORD require of you but to do justice, and to love kindness, and to walk humbly with your God?
I'm sorry you hear the devil all of the time. That must suck. If you draw near to God, then He will draw near to you.
James 4:7-8
7Submit yourselves therefore to God. Resist the devil, and he will flee from you.
8Draw near to God, and he will draw near to you. Cleanse your hands, you sinners, and purify your hearts, you double-minded.
Sometimes I wish that God would talk to me directly and tell me exactly what He wanted me to do with my life in every specific moment. However, if you read the Old Testament when God did just that through the prophets, often times many of the people refused to do what they were told to do and often punished for directly disobeying God one way or another. What God wants from all of us is to follow His commandments, to give Him thanks in everything, to spread the gospel and make disciples, and to love God with everything we have along with people. He wants us to do stuff like give to the poor and to take care of widows and orphans if we can.
1 Thessalonians 5:18
give thanks in all circumstances; for this is the will of God in Christ Jesus for you.
Matthew 28:18-20
And Jesus came and said to them, “All authority in heaven and on earth has been given to me.
19Go therefore and make disciples of all nations, baptizing them inbthe name of the Father and of the Son and of the Holy Spirit, 20teaching them to observe all that I have commanded you. And behold, I am with you always, to the end of the age.”
John 14:15-17
“
If you love me, you will keep my commandments. 16And I will ask
the Father, and he will give you another Helper,f to be with you forever, 17even the Spirit of truth, whom the world cannot receive, because it neither sees him nor knows him. You know him, for he dwells with you and will be
g in you.
God sends the Holy Spirit to be with all Christians. the Holy Spirit doesn't typically manifest as hearing voices that are distracting and telling lies, but the Holy Spirit is still there. I think in Isaiah, this passage talks about the Holy Spirit resting on Jesus and describes in depth what the Holy Spirit is in 7 parts.
Isaiah 11:1-5
The Righteous Reign of the Branch
1There shall come forth a shoot from the stump of Jesse,
and a branch from his roots shall bear fruit.
2And
the Spirit of the LORD shall rest upon him,
the Spirit of wisdom and understanding,
the Spirit of counsel and might,
the Spirit of knowledge and the fear of the LORD.
3And his delight shall be in the fear of the LORD.
He shall not judge by what his eyes see,
or decide disputes by what his ears hear,
4but with righteousness he shall judge the poor,
and decide with equity for the meek of the earth;
and he shall strike the earth with the rod of his mouth,
and with the breath of his lips he shall kill the wicked.
5Righteousness shall be the belt of his waist,
and faithfulness the belt of his loins.
John 6:28-29
28Then they said to him, “What must we do, to be doing the works of God?”
29Jesus answered them, “
This is the work of God, that you believe in him whom he has sent.”
2 John 1:6
And this is love, that we walk according to his commandments; this is the commandment, just as you have heard from the beginning, so that you should walk in it.
Other than the the things that God wants everyone to do, to know specifically what God wants you to do is hard to know. There is one time where I think that God spoke to me in a dream, and really the only thing He told me to do that was individualized and yet not was that I needed to forgive my mother and ask her for forgiveness, and to realize that I was not without sin. But both of those things are really already in the Bible, we as Christians are supposed to forgive and and ask for forgiveness, if not from people, then at least from God. And of course we are all sinners.If you want God to tell you what to you, then spend more time reading the Bible. The Bible is the word of God. God sends the Holy Spirit to be with you through all of your struggles. I think this one Psalm is interesting. It talks about how God knows everything before it happens, and also that no matter where you are, He is there. I'm not sure exactly what Sheol means though, some interpret it to be simply death while others think it is hell. I don't know. But the point is that God is everywhere.
Psalm 139:1-12
1O LORD, you have searched me and known me!
2You know when I sit down and when I rise up;
you discern my thoughts from afar.
3You search out my path and my lying down
and are acquainted with all my ways.
4Even before a word is on my tongue,
behold, O LORD, you know it altogether.
5You hem me in, behind and before,
and lay your hand upon me.
6Such knowledge is too wonderful for me;
it is high; I cannot attain it.
7Where shall I go from your Spirit?
Or where shall I flee from your presence?
8If I ascend to heaven, you are there!
If I make my bed in Sheol, you are there!
9If I take the wings of the morning
and dwell in the uttermost parts of the sea,
10even there your hand shall lead me,
and your right hand shall hold me.
11If I say, “Surely the darkness shall cover me,
and the light about me be night,”
12even the darkness is not dark to you;
the night is bright as the day,
for darkness is as light with you.
Sometimes if people turn against God then He will hide His face from them, but as soon as they repent and turn back, He no longer hides His face from them.
Ezekiel 39:25-29
The LORD Will Restore Israel
25“Therefore thus says the Lord GOD: Now I will restore the fortunes of Jacob and have mercy on the whole house of Israel, and I will be jealous for my holy name.
26They shall forget their shame and all the treachery they have practiced against me, when they dwell securely in their land with none to make them afraid,
27when I have brought them back from the peoples and gathered them from their enemies’ lands, and through them have vindicated my holiness in the sight of many nations.
28Then they shall know that I am the LORD their God, because I sent them into exile among the nations and then assembled them into their own land. I will leave none of them remaining among the nations anymore.
29And I will not hide my face anymore from them, when I pour out my Spirit upon the house of Israel, declares the Lord GOD.”
Deuteronomy 32:17-22
17They sacrificed to demons that were no gods,
to gods they had never known,
to new gods that had come recently,
whom your fathers had never dreaded.
18You were unmindful of the Rock that bore
e you,
and you forgot the God who gave you birth.
19“The LORD saw it and spurned them,
because of the provocation of his sons and his daughters.
20And he said, ‘I will hide my face from them;
I will see what their end will be,
for they are a perverse generation,
children in whom is no faithfulness.
21They have made me jealous with what is no god;
they have provoked me to anger with their idols.
So I will make them jealous with those who are no people;
I will provoke them to anger with a foolish nation.
22For a fire is kindled by my anger,
and it burns to the depths of Sheol,
devours the earth and its increase,
and sets on fire the foundations of the mountains.
James 1:27
Religion that is pure and undefiled before God the Father is this: to
visit orphans and widows in their affliction, and to keep oneself unstained from the world.
Hebrews 13:15-16
15Through him then let us continually offer up a sacrifice of praise to God, that is, the fruit of lips that acknowledge his name.
16Do not neglect to do good and to share what you have, for such sacrifices are pleasing to God.
