Man was created with Free Will and The Measure Of Faith.
Because of Original Sin each of us are born in sin which is essentially a Spirit Of Rebellion.
As a result, all of our thoughts proceed from these foundational influences. Even those thoughts which, on the surface, do not appear connected to those influences are in fact indirectly connected to them.
One of the great deceptions of the enemy, which is founded in Original Sin and the Spirit Of Rebellion that it engendered, is that we are capable of Independent Thought.
If our thoughts proceed from the Knowledge Of God they are good.
If our thoughts proceed from the Spirit Of Rebellion they are evil.
It is not complicated but it is profound and it is inescapable.
This leaves every person with the Free Will choice as to whether to move toward God or away from God (which is to move toward Satan).
The default state and direction in man is
➛ away from God
➛ into bondage
➛ into suffering
➛ into heartache
➛ into death
The Gospel is God's attempt to inform us and enable us
➛ to change directions
➛ to be established in Him
➛ to be reprogrammed
➛ to be One with Him
➛ to love one another
➛ to explore Eternal Life in health and prosperity
So, if you think you have Independent Thoughts you are deceived by your Spirit Of Rebellion.
You have the Free Will to repent - which is to reject your Spirit Of Rebellion and receive a New Spirit which is the Spirit Of Christ and begin pursuing the Mind Of Christ.
All you have to do is call on the name of the Lord Jesus Christ and He will do the work.
