Yes, Jesus is enough. When you look at Him you see God The Son in all His fullness. The second half of Colossians 1:15 says:
He existed before anything was created and is supreme over all creation.
Jesus pre-existed Creation. That's easy to grasp if your theology begins with an understanding that Jesus is God in flesh.
He is the Alpha - the beginning. All things come from Him.
He is the Word - the creative force of God. 'Then God said' is the words used on each day of Creation. The Word of Jesus creates and changes everything.
He is Sovereign - above all things! There is no higher height. There is nothing to fear when Jesus is with you.
Jesus is more than enough. He is complete and offers you completeness in Him. Wouldn't you like that?
