Col 3:4 When Christ, who is our life, shall appear, then shall ye also appear with him in glory. When does Christ become Our Life ? Now many believe that Christ does not become Our Life until we become Believers in Him ! This assumption is dead wrong, in fact we cant believe on Him accept He is Our Life already, for without Him we can do nothing Jn 15:5 I am the vine, ye are the branches: He that abideth in me, and I in him, the same bringeth forth much fruit: for without me ye can do nothing. Christ has been the True Believers Life long before they believed ! They always had Life in Him as He was always their Mediator Head, and John writes Jn 1:4 In the beginning was the Word, and the Word was with God, and the Word was God. 2 The same was in the beginning with God. 3 All things were made by him; and without him was not any thing made that was made. 4 In him was life; and the life was the light of men. And they were Chosen IN HIM when ? Eph 1:4 4 According as he hath chosen us in him before the foundation of the world, that we should be holy and without blame before him in love: Christ was the believers Life and they had Life in Him, while they were dead in trespasses and sins and unbelief ! Dont let this alarm you, because the same was True of their natural life in Adam in the beginning, Adam as their Natural Head was their Life before God before they any physical being at all ! The only reason why we were born naturally is because we had physical life already purposed in Adam Acts 17:26 26 And hath made of one blood all nations of men for to dwell on all the face of the earth, and hath determined the times before appointed, and the bounds of their habitation; And its no difference in the Last Adam, Believers receive Spiritual Life because Christ was their Head and Life before they had any Spiritual being, but just as sure their natural life was manifested out of Adam from natural birth, so likewise their Spiritual life shall be manifested out of Christ from Spiritual Birth !
