Puritan pastor Thomas Manton reminds us that at conversion a Christian is given a new heart designed to battle sin, and grow in Christ-like-ness….
“There is a form of grace introduced into the soul, that suits with every point of the law. The heart is framed to resist every sin, to observe all that God hath commanded. A new born infant has all the parts of a man, though not the strength and bulk; so every Christian in regeneration. Men may be born without hands or feet, but the new creature never comes out maimed or imperfect. It is small and weak at first, but it grows and gathers strength.”
