“The sinner is free, but free in ONE DIRECTION ONLY — free to fall, free to sin. As the Word expresses it: “For when ye were the servants of sin, ye were FREE FROM righteousness” Rom. 6:20. The sinner is free to do as he pleases, always as he pleases (except as he is restrained by God), but his pleasure is to sin.
Does it lie within the power of the sinner’s will to yield himself up to God? Let us attempt an answer by asking several others: Can water (of itself) rise above its own level? Can a clean thing come out of an unclean? Can the will reverse the whole tendency and strain of human nature? Can that which is under the dominion of sin originate that which is pure and holy? Manifestly not. If ever the will of a fallen and depraved creature is to move God-wards, a Divine power must be brought to bear upon it which will overcome the influences of sin that pull in a counter direction.
This is only another way of saying, “No man can come to me, except the Father which hath sent me, draw him” John 6:44. In other words, God’s people must be made willing in the day of his power Psa. 110:3.”
