Matthew 27:3 Then when Judas, his betrayer, saw that Jesus was condemned, he changed his mind and brought back the thirty pieces of silver to the chief priests and the elders, 4 saying, "I have sinned by betraying innocent blood." They said, "What is that to us? See to it yourself." 5 And throwing down the pieces of silver into the temple, he departed, and he went and hanged himself. 6 But the chief priests, taking the pieces of silver, said, "It is not lawful to put them into the treasury, since it is blood money." 7 So they took counsel and bought with them the potter's field as a burial place for strangers. 8 Therefore that field has been called the Field of Blood to this day. 9 Then was fulfilled what had been spoken by the prophet Jeremiah, saying, "And they took the thirty pieces of silver, the price of him on whom a price had been set by some of the sons of Israel, 10 and they gave them for the potter's field, as the Lord directed me."
Judas was a thief dominated by Satan who displayed a love of money by his actions (John 12:6; Luke 22:3; 1 Timothy 6:10). He sinned by being deceitful and taking money to betray his friend and Lord, Jesus. Judas saw the results of his sin and felt remorse - he changed his mind about selling out Jesus for thirty pieces of silver. The word translated remorse or change of mind means to have regrets about something and wish what was done could be undone. Judas couldn't change what he did but tried to relieve his regret by bringing the betrayal money back to the chief priests and elders. They couldn't by law put the blood money back in the treasury and bought the potter's field. Indirectly Judas bought the potter's field, went there, hung himself and ended by doing a face plant and bursting open in that very field (Matthew 27:5; Acts 1:18). Please note what happens when Satan talks to us. Satan prompted Judas to betray Jesus, but didn't tell him how bad it would be - that Jesus would be condemned to death. When Judas was regretting what he had done, Satan again prompted an action that would lead to death. He prompted Judas to hang himself to relieve his despair, an act that couldn't be undone.
What should we do when we think about sinning? We should think like Moses in Hebrews 11:24-26. Moses thought correctly that the pleasures of sin are fleeting and considered suffering for Christ worth far more than the pleasures of sin. Our sins consequences are far worse than we originally think and only bring regret and the desire to undo what we did. When we are tempted to sin, we need to remember that the consequences of sin are far greater than the temporary satisfaction of sin.
What should we do after we have sinned and are experiencing the regret of doing our sin? We should immediately go to Jesus, confess our sin, receive His forgiveness, make restitution if we can and begin to obey His teaching. We will experience freedom from the regret of sin and go on with our life in the freedom of forgiveness.
One last, but very important lesson from our text today is this. God's word happens! We can count on God doing what He says. His word never fails. We can trust Him completely to do all He says in His written word. If we learn His word, the Bible, we will not be deceived by Satan to do what brings great regret.
