I keep having bad thoughts towards God , how do I know is not me , Do God knows that I don't want to think this way? Do I have to feel scare ? Is bad if I ignored my bad thoughts..
Bad thoughts cannot just be ignored. They have to be overcome.
The scripture assures the believer that God knows more about us than we know about ourselves. In Romans 8, are the words of the believer who finds themselves doing bad things that they don't want to do.
In verse 22 are the words of the believer, "I delight in the law - the instructions of the Lord, according to my inward man."
Another verse is Psalms 119:165, "Those who love Your law - instructions (for good and happy life) O Lord, have great peace, and nothing causes them to stumble (make a mistake)."
Another verse is Jeremiah 15:16, "Your words were found and I ate them."
God's word uses idioms and metaphors as forms of expression. The believer eats God's word by ruminating or meditating or muttering it to oneself.
Psalm 1:1, 3 says, "Blessed is the one whose delight is in the law of the Lord, and in His law he meditates day and night. And that one will be like a tree firmly planted by the rivers of water, which yields its fruit in season, and it's leaf does not wither; and whatever that one does shall prosper.'
Back to Jeremiah 15:16, "I ate them and Your words became for me a joy and the delight of my heart. For I have been called by Your Name."
Concerning the believer described in Romans 8, It is most appropriate to use the words of another believer that we can relate to.
The Bible is available to use in the time of temptation, test, trial or adversity.
Jesus Himself used the scriptures when he was tempted of the devil in Matthew 4:2-11.
The Bible states in Hebrews 6:12, that believers are to "be imitators of those who through faith and patience inherit the promises."
Jesus said in Luke 9:23, to follow after Him, or to imitate His example. He also said in Matthew 11:29, "Take My yoke upon you and learn of Me."
The yoke that Jesus spoke of was in terms of a training yoke that is placed upon an inexperienced farm animal. Like a farmer places the yoke upon a farm animal to learn how to pull the plow to make furrows for planting seed.
So the training yoke is the instructions within the Word of God on how to do things that by being obedient, will produce beneficial results in life.
The first temptation in Matthew 4, was when Jesus had fasted and became hungry, the temptation was to turn the stones into bread.
Jesus quoted from the old testament, Deuteronomy 8:2-3, "You shall remember all the way which the LORD your God has led you in the wilderness these forty years, that He might humble you, testing you, to know what was in your heart, whether you would keep His commandments or not."
"He humbled you and let you be hungry, and fed you with manna which you did not know, nor did your fathers know, that He might make you understand that man does not live by bread alone, but man lives by everything that proceeds out of the mouth of the LORD."
Quoting just of portion of that in Matthew 4:4, Jesus said, "Man does not live by bread alone but by every Word that proceeds out of the mouth of God."
From that example that Jesus gave when tempted, it is understood that believers must speak what is relevant to the situation of what God's Word says, in order to overcome a test, a temptation, a trial, or an adversity.
When you notice that you are thinking bad thoughts towards God, then it's time to purposely think good thoughts toward God. There's a scripture that will be useful. The entire of Psalms 103. It begins "Bless the Lord O my soul and all that is within me, Bless His holy Name."
The following verses are a list of reasons to bless the Lord. Read them outloud. When you are doing that, your thoughts cannot think about anything bad.
There is also the scriptures in Philippians 4:8-9 "Brethren, whatever is true, whatever is honorable, whatever is right, whatever is pure, whatever is of lovingkindness and gracious, whatever is of good report, if there is any excellence and if anything worthy of praise unto God, let your mind think on these things; and the God of peace shall be with you."
Then Philippians 4:7 "And the peace of God which surpasses all reasonings shall guard your heart and your mind in Christ Jesus."
Then 2 Corinthians 10:4-5 "For the weapons of our warfare are not of the outward natural man, but they are of the inner spiritual man, such weapons which are mighty through God to the pulling down of mental or emotional strongholds.
And to cast down every unrighteous reasoning and every vain imagination that would seek to exalt themselves against the knowledge of God.
And to arrest, and bring into captivity every such thought to be in subjection to the obedience of Christ the Anointed One, and His anointing."
1 Kings 3:9, "So give your servant a hearing and understanding heart to judge and discern the difference between good and evil."
Romans 12:21, "To overcome all evil with good."
Psalm 106:1, "Praise You O Lord for you are good, for Your lovingkindness endures forever."
