What does it really mean to believe on the Lord Jesus Christ? The key word that runs through this chapter is believe — used seven times — because believing is the key that connects every promise Jesus makes to us. Now, believing isn't just accepting the historical facts about Jesus; it's a change that takes place in the deepest part of you, where Christ becomes what your life is about and makes you into a new creature. That comes about through the new birth. Jesus said, "...he that believeth on me, the works that I do shall he do also..." — and that word is shall, not will — meaning it's not optional or something you decide to do after you're saved; it's what becomes your nature when Christ is in you. He also promised that even after going to the Father, he would still be present with us, still working, and that "...if ye shall ask anything in my name, I will do it." But that promise is conditioned on our walking in his steps, keeping his commandments out of love, and living as his representatives in this world. The only way to really know what Jesus is like and examine whether you're truly like him, is to read and study the Word of God — particularly the Gospels — and let the Spirit of God bear witness with your spirit that you are truly his - or not.
