If you have come to know Jesus personally, as your savior, you can trace your faith to a prayer he made on your behalf. It is recorded in the book of John, chapter 17:
Verse 20: "I do not ask for these only, but also for those who will believe in me through their word, that they may all be one, just as you, Father are in me, and I in you, that they also may be in us, so that the world may believe that you have sent me."
Jesus is about to be betrayed by Judas...He knows the soldiers are coming for him...and yet he is praying for his disciples and for us who would eventually believe in him. Jesus seemed to be always thinking about His Father and about us and about how to bring us to the Father and how to bring the Father to us.
And now we who have believed are the carriers of these truths...that others might believe through our sharing of the word with them. For there are others for whom Jesus prayed in chapter 17 that must hear and believe!
