John 14:21

He who has My commandments and keeps them, it is he who loves Me. And he who loves Me will be loved by My Father, and I will love him and manifest Myself to him. 

Love is the curtain rod that all the promises of God hangs on.  The commandments of God are meant to set us free and not be burdens.  When we love Jesus, we love God and the truth of God will set us free from sin and death.  As we draw closer to Jesus and God the more we will gain understanding and He will manifest (make clear) Himself to us.
