Observe with much comfort that the Lord Jesus Christ gives this repentance to the most unlikely people in the world. He is exalted to give repentance to Israel. To Israel! In the days when the apostles thus spoke, Israel was the nation which had most grossly sinned against light and love, by daring to say, “His blood be on us and on our children.” Yet Jesus is exalted to give them repentance! What a marvel of grace! If you have been brought up in the brightest of Christian light and yet have rejected it, there is still hope. If you have sinned against conscience and against the Holy Spirit and against the love of Jesus, there is yet space for repentance. Though you may be as hard as unbelieving Israel of old, softening may yet come to you, since Jesus is exalted and clothed with boundless power. For those who went the furthest in iniquity and sinned with special aggravation, the Lord Jesus is exalted to give to them repentance and forgiveness of sins. Happy am I to have so full a gospel to proclaim! Happy are you to be allowed to read it!
