"For you have died, and your life is hidden with Christ in God. When Christ who is your life appears, then you also will appear with him in glory." - Colossians 3:3-4 ESV
Your life (zōē Strong's G2222) has been hidden (kryptō (G2928) in Christ. It has been encrypted in Christ. Hidden like a secret message has been hidden.
Christ's glory unlocks the code. Christ's glory is His character and nature. It is His deity and His humanity. It is His role in history. It is the true account of His actions.
"And after six days Jesus took with him Peter and James, and John his brother, and led them up a high mountain by themselves. And he was transfigured before them, and his face shone like the sun, and his clothes became white as light. And behold, there appeared to them Moses and Elijah, talking with him." - Matthew 17:1-3 ESV
It seems that Colossians 3 gives us the doctrine to 'explain' this passage. These two men appear and no introductions are necessary. It is obvious who they are because Jesus is being glorified in that place.
Knowing Jesus decodes your life. That is partially why people can get saved but then go on to do infamous things. Then others question, 'Were they saved or not? If salvation has meaning how could that person go back to dealing drugs? If salvation is real how come that person lives the same way they did before?' The zoe life was never revealed. That didn't nullify their salvation. Salvation is a moment of believing. Only God knows in those cases.
Identity remains a mystery until Christ is revealed in His glory. Oh, But when He Is revealed the zoe is revealed also.
