I call heaven and earth to record this day against you, that I have set before you life and death, blessing and cursing: therefore choose life, that both thou and thy seed may live: / That thou mayest love the LORD thy God, and that thou mayest obey his voice, and that thou mayest cleave unto him: for he is thy life, and the length of thy days: that thou mayest dwell in the land which the LORD sware unto thy fathers, to Abraham, to Isaac, and to Jacob, to give them.Beings with no free will would never have choices set before them. Also, Jesus would never have had to die for the sins of humanity, if they had no free will to control their actions one way or another.
— Deuteronomy 30:19-20
They answered him, "We are Abraham's descendants and have never been slaves of anyone. How can you say that we shall be set free?" Jesus replied, "Very truly I tell you, everyone who sins is a slave to sin."
Romans 6:15-18 What then? Shall we sin because we are not under the law but under grace? By no means! Don't you know that when you offer yourselves to someone as obedient slaves, you are slaves of the one you obey-whether you are slaves to sin, which leads to death, or to obedience, which leads to righteousness? But thanks be to God that, though you used to be slaves to sin, you have come to obey from your heart the pattern of teaching that has now claimed your allegiance. You have been set free from sin and have become slaves to righteousness.
We have no ability in ourselves to choose for God. We can't come to God unless the Holy Spirit enlightens us and draws us.
