The Scriptures teach that believing in Jesus does not take away our free will, .
Free will is to do the will of the unseen father who works in and with His creation to both will and do his good pleasure.(imputed righteousness) We should do without murmuring, comparing ourselves to ourselves in selfish pride..
Free will is just as he created a will...... to be subject to Him. Mankind gave that over in the garden, God gave them over with a strong delusion to do that which they should not . Becoming a slave to the will of the god of this world... lust of the eyes. lust of the flesh needed to build up false pride.
Its the kind of food of doing the will of another that the apostles knew not of.
John 4:33-35 King James Version (KJV) Therefore said the disciples one to another, Hath any man brought him ought to eat? Jesus saith unto them, My meat is to do the will of him that sent me, and to finish his work.
