Well, there isn't a magic formula. The truth is, left to our own devices, it would be impossible for us to live a Christian life. Our will is naturally inclined to be rebellious against God. Our hearts are hardened and our minds are deranged by sin. If it was a question of, what can I do under my own power, then we would all still be headed to hell.
That was the whole point of Jesus going to the cross, because none of us could possibly live up to Gods standard. We all deserve death and hell. This is the point:
Philippians 4:13
I can do all things through him who strengthens me.
and
John 15:5
"I am the vine; you are the branches. If a man remains in me and I in him, he will bear much fruit; apart from me you can do nothing."
We can't do anything apart from God. We will fail every single time. It is only through Christ that living a Christian life becomes attainable. How do we do that? BY the guidence of the Holy Spirit:
John 16:13
But when he, the Spirit of truth, comes, he will guide you into all truth. He will not speak on his own; he will speak only what he hears, and he will tell you what is yet to come.
The Spirit guides us into all truth. Meaning, we can depend on Him for everything. He leads us in prayer:
Romans 8:26
Likewise the Spirit helps us in our weakness. For we do not know what to pray for as we ought, but the Spirit himself intercedes for us with groanings too deep for words.
He is the Spirit of our sonship:
Romans 8:15
For you did not receive a spirit that makes you a slave again to fear, but you received the Spirit of sonship. And by him we cry, "Abba, Father."
He causes us to bear much fruit:
Galatians 5:22
But the fruit of the Spirit is love, joy, peace, patience, kindness, goodness, faithfulness,
What should we ask God to do for us? Jesus Himself gave us the example:
Luke 22:42
saying, “Father, if you are willing, remove this cup from me.
Nevertheless, not my will, but yours, be done.”
Pray that in everything, His will be done. Pray that He crushes your will and puts His in its place. Pray that He gives you faith. Pray that He pours His love into your heart. Pray to love Him with all your heart, mind spirit and strength. Pray to love your neighbor. Everywhere you lack, pray for intercession. God will grant you these gifts, He will show you how to love Him, and how to live a Christian life. Just have faith and trust Him in all things and He will provide. Let the Spirit guide you in this:
1 Thessalonians 5:17
pray without ceasing,
Hope this helps. God bless.
Currently, I am not a Christian. At one point in my life I thought I was but I've fallen so far from God that I'm not even sure I was ever serious about Christianity to begin with. I want to be a Christian but I'm not sure how

I believe in the Bible, I believe that it is innerant, I believe in God, I believe in Jesus, I believe that Jesus suffered and died on a cross to defeat sin so that we may all be saved IF we choose to die to ourselves and live for him, I believe that he was miraculously resurrected and ascended to His Kingdom where he now sits at the right hand of God the Father, I believe that we should want to be saved not just so that we can go to Heaven when we die but so that we can have a real, close, personal, intimate relationship with our Creator, I believe that all of my sins can be forgiven and that God wants to have a relationship with me too, etc. I believe all of this, I know all of it is true and that I need to do this because I want to and because it's right, but I don't know how. Probably sounds weird, huh? I know

It all looks/sounds/seems so easy but something is keeping my from taking the leap and just giving myself to him. Maybe I'm feeling like the post-salvation lifestyle is too difficult? Maybe I'm afraid that, like every time I THOUGHT I was a Christian in the past and failed, I'm just going to go with the motions or think that I'm saved and then back off or fall away again after a few months? I don't know. I really don't know what it is. All I know is that the Bible and all that it contains is absolutely undeniably true and that I want to live my life as a child, servant, and friend of the God of this universe. Please pray for me. I don't want to waste anymore time. I just feel so detached, like my heart is so hard. I'm afraid that I won't be able to take this step.
