What Jesus came to do for us is just TOO large for the human mind to comprehend, even angels desire to look into these things (see 1 Peter 1:12).
It’s all because of Him that we have access to the Father without any sense of guilt or condemnation. Our lives are hidden in Christ and Christ in God, that’s to let you know that we are double protected in Christ and nothing can snatch us away from His hands. We are so mingled together that you can’t separate me from Christ or Christ from me.
