Colossians 3:4 ESV
When Christ who is your life appears, then you also will appear with him in glory.
No one can see the coming glory and wonder of what God has in store for us. We are unable to conceive our transformation into the full revelation of Christ at His coming. This revelation will include the revealing of the children of God, for we will be like Him.
He is our life because He has given His life. He is our life when we receive it. He is our life when we live it.
