Intimacy has been defined as the 'joint participation in truth.' It is two people being completely open and honest with one another, making themselves vulnerable to one another. God has already made Himself vulnerable to each of us and He is always open and honest. We are the ones who hide or deceive or put up a false front. 1 John 1:5-10 says, 'This is the message which we have heard from Him and declare to you, that God is light and in Him is no darkness at all.6 If we say that we have fellowship with Him, and walk in darkness, we lie and do not practice the truth.7 But if we walk in the light as He is in the light, we have fellowship with one another, and the blood of Jesus Christ His Son cleanses us from all sin.8 If we say that we have no sin, we deceive ourselves, and the truth is not in us.9 If we confess our sins, He is faithful and just to forgive us our sins and to cleanse us from all unrighteousness.10 If we say that we have not sinned, we make Him a liar, and His word is not in us.' To walk in the light means to live a life of openness and honesty with both God and man. This is the key to intimacy.
We suggest you read through a series of lessons we have put together called 'Life in the Community of Light.' They can be found on Shelf 12 of the Apostolic Free Library.
