Matthew 9:1 And getting into a boat he crossed over and came to his own city. 2 And behold, some people brought to him a paralytic, lying on a bed. And when Jesus saw their faith, he said to the paralytic, "Take heart, my son; your sins are forgiven." 3 And behold, some of the scribes said to themselves, "This man is blaspheming." 4 But Jesus, knowing their thoughts, said, "Why do you think evil in your hearts? 5 For which is easier, to say, 'Your sins are forgiven,' or to say, 'Rise and walk'? 6 But that you may know that the Son of Man has authority on earth to forgive sins"- he then said to the paralytic- "Rise, pick up your bed and go home." 7 And he rose and went home. 8 When the crowds saw it, they feared and glorified God, who had given such authority to men.
Matthew 4:13 informs us that Capernaum was Jesus' home base in fulfillment of Scriptures. Notice what Jesus saw in those bringing the paralytic to Jesus, their faith (not their works). Jesus' response to faith was to forgive the paralytic's sin. The most important thing that can happen to us is not the healing of our body, but forgiveness of our sin. Why is this? If we have forgiveness of sin we will eventually have a brand new body in a new heavens and earth (1 Corinthians 15:50-56; Revelation 21:1-4). If we have a healed body and no forgiveness of sin, we have a future of eternal torment (Luke 16:19-31; Revelation 21:8).
Jesus knew what the scribes were saying in their hearts. He also knows what we are saying in our hearts. We cannot hide from God. He knows all about us and still loves us. We can always go to God no matter what we have done - He loves us sin and all (Romans 5:8). Jesus responded to the evil thoughts of the scribes' hearts and sought to expose their sin (they were saying Jesus was blaspheming by forgiving sins, which only God could do and thus sinning) for them to see by asking them why they were thinking evil in their hearts. Jesus is always seeking to make our sin known to us so that we can turn from it rather than be destroyed by it. Jesus also sought to show the scribes that He had authority to forgive sin and was not blaspheming. He proved He had authority to forgive sins by healing the paralytic's body.
When Jesus exposes our sin it is because He loves us and wants us to seek His forgiveness. We seek His forgiveness by faith, not by works. When we repent of our sin by agreeing with Jesus that we have sinned, when we confess our sins to Him, then we receive His forgiveness and cleansing from all sin. Please note that we are forgiven by faith, not by works. Jesus paid for all our sins by His work (His death) on the cross. If we tried to gain forgiveness by works, we would never gain it because we could never do enough works.
What are we to do with what this scripture teaches us? Come to Jesus to receive forgiveness of our sins. Remember what our Lord taught us through the Apostle John, "If we confess our sins, He is faithful and just to forgive us our sins and cleanse us from all unrighteousness." 1 John 1:9. I call 1 John 1:9 my sin emergency number, 119. After I confess my sin, I know I am restored to fellowship with the Lord. I don't go on in guilt, I go on joyful that I am forgiven, cleansed and restored to service.
