Jesus lived a perfectly sinless life on this Earth and remains perfect. Jesus is simultaneously 100% God and 100% man. He is the God Man. Several factors go into understanding this. One is the Virgin Birth. Read Isaiah 7:14: “Therefore the Lord Himself will give you a sign: Behold, the virgin shall conceive and bear a son, and shall call his name Immanuel.” Matthew 1:20 says, “...’Joseph, son of David, do not be afraid to take Mary as your wife, for that which is conceived in her is of the Holy Spirit.’” Jesus was not conceived by a sinful man but by the perfection of the Holy Spirit of God. This allowed Him to be born sinless. Sin has been passed down through the man since Adam because Adam sinned. “Therefore, just as though through one man (Adam) sin entered the world, and death through sin, and thus death spread to all men, because all sinned” (Romans 5:12). Since Jesus was born and remained sinless, He could then offer the gift of righteousness to all because through His righteousness. “For if by the one man's offense death reigned through the one, much more those who received abundance of grace and the gift of righteousness will reign in life through the One, Jesus Christ” (Romans 5:17). From birth to the cross, Jesus lived a perfectly sinless life because of how He dealt with the sin around Him. He fought sin perfectly through the use of prayer, the Word, and seeking God’s will entirely. However, He understands our dilemma with sin and its struggles because He too faced those struggles. Hebrews 4:15 says, “For we do not have a High Priest (Jesus) who cannot sympathize with our weaknesses, but was in all points tempted as we are, yet without sin.” Only on the Cross was sin a part of Jesus, and that wasn’t even His own sin, but ours! 2 Corinthians 5:21 says, “For He (God the Father) made Him who knew no sin (Jesus) to be sin for us, that we might become the righteousness of God in Him.” Because Jesus loves us, He came born of a virgin, lived a sinlessly perfect life, and died the death we should have so that we could trade our sin for His righteousness and receive the gift of salvation.
