Believing, repenting, and the like, are the product of the new nature; and can never be produced by the old corrupt nature... as the child cannot be active in his own generation, so a man cannot be active in his own regeneration. The heart is shut against Christ: man cannot open it, only God can do it by his grace.
Thomas BostonCall it no more free-will, but slavish lust; free to evil, but free from good, till regenerating grace loosens the bands of wickedness.
Thomas Boston
