Their prophets therefore despaired of ever bring them to do good. This was what they aimed at; they persuaded them to cease to do evil and learn to do well, but could not prevail. They had so long been used to do evil that it was next to impossible for them to repent, and amend, and begin to do good. Note, Custom in sin is a very great hindrance to conversion from sin. The disease that is inveterate is generally thought incurable. Those that have been long accustomed to sin have shaken off the restraint of fear and shame; their consciences are seared; the habits of sin are confirmed; it pleads prescription; and it is just with God to give those up to their own hearts’ lusts that have long refused to give themselves up to his grace.
Sin is the blackness of the soul, the deformity of it; it is its spot, the discolouring of it; it is natural to us, we were shapen in it, so that we cannot get clear of it by any power of our own. But there is an almighty grace that is able to change the Ethiopian’s skin, and that grace shall not be wanting to those who in a sense of their need of it seek it earnestly and improve it faithfully.
Lord, help us to repent and come to you to cleanse us from all wickedness. Amen.
