37 Then Pilate said to Him, “So you are a king?” Jesus answered, “You say that I am a king. For this purpose I was born and for this purpose I have come into the world—to bear witness to the truth. Everyone who is of the truth listens to my voice.” 38 Pilate said to him, “What is truth?” After he had said this, he went back outside to the Jews and told them, “I find no guilt in Him.” ~ John 18:37-38
When Jesus stood before Pilate, He told him that He came to bear witness to the truth. Pilate then asked, what is truth? Well, here is truth. For God so loved the world that He gave His only begotten Son to die for each and every one of us (John 3:16). That is Truth.
He promised to come into the world as a baby through the virgin (Isaiah 7:14), and He did. He promised to redeem mankind with His own blood (Isaiah 53:5-12), and He did. He promised to give us His Holy Spirit as a seal, and He did.
All of His promised He has kept. But there is still one more that is yet to be fulfilled. He has promised to come back to get us so that we believers may live with Him forever and ever without end.
If you would like to spend eternity with Jesus, here is how to do it. Come to Him in repentance. If you call out to Christ, He will answer you. If you ask for forgiveness, He will forgive. It is not the words so much as it is your remorse for your sin and your desire to please the Savior.
