Hidden

Colossians 3:1-4 NIV
1 Since, then, you have been raised with Christ, set your hearts on things above, where Christ is, seated at the right hand of God. 2 Set your minds on things above, not on earthly things. 3 For you died, and your life is now hidden with Christ in God. 4 When Christ, who is your life, appears, then you also will appear with him in glory.

Being raised with Christ, we are lifted into new life. A new perspective is now available to us. We live on earth, but our understanding has opened as our spirit is made new in the life of Christ. Just as we are receiving eternal life in spirit through the Holy Spirit, our bodies will receive eternal life when Jesus returns. That is when we will become fully human as God intended.
Being "hidden" with or in Christ speaks to our inclusion in the body of Christ. Through His grace and mercy, we have been washed in His blood.  We have been given white robes of His righteousness when we accept and put on Christ, and our sins remembered no more. When God looks our way, He sees us through the eyes of His loving Son. The old is hidden and the new is being revealed.
