Ye are of God, little children, and have overcome them: because greater is he that is in you, than he that is in the world. John 4:4"
Apostle John by the revelation of God has given the saints a valuable insight into who they are on the inside. You are a spirit living in a body; therefore, when you become born again, the Holy Spirit recreates your spirit to conform to the nature of God so that He can live in your spirit.
You become a child of God and hence John 10:34. You carry God inside you in the person of the Holy Spirit; therefore, you are greater on the inside than anything in the world. You are big on the inside, so give cooperation to the Holy Spirit to teach you how to beat the world and those in the world.
You cannot fail because the Holy Spirit on the inside of you is above all and cannot fail. Keep saying to yourself, "I am big on the inside for greater is He who lives in me than anything in the world"; as you say this, boldness will well up in you to overcome any obstacle that confronts you.
Hallelujah!
