The call to follow Christ is strictly his choice. The condition for that choice is also His. Hence scripture says in Isaiah’s prophecy: “My ways are not your ways, and my thoughts not your thoughts.” I suppose those around must wonder why Christ calls Matthew. They also must wonder how he chooses to dine with tax collectors and sinners. This is the mystery of God. God is not so much concerned about our sins than his desire to save your from our sins. Do not let your opportunity to be called to salvation by God today be smeared by the guilt of your sin.
