The fourth principle is that we all must be seeing the same thing. God has spoken to us in the book of Ephesians about a mystery, a revelation of Himself, a plan. If we are going to have fellowship one with another, we will have the same revelation. There must be the same aim before us. We must see Jesus, and Jesus alone. If we look to others, we will be divided in what we believe. If we try to know God in our minds, there is no way that our doctrines will be the same, but "if we do His will, we will know His doctrine" (John 7:17). So, to see the same thing is one of the principles of spiritual fellowship.
If each member of the body of Christ is looking to God and seeing spiritually, then we go on to experience what we see, and this brings forth a fuller expression of fellowship with God. The revelation is the Lord Jesus Christ, not in the letter of the word but in the life of the Spirit.
