Charles Spurgeon Commentary Colossians 2:2

"that their hearts may be comforted, they being knit together in love, and unto all riches of the full assurance of understanding, that they may know the mystery of God, [even] Christ," — Colossians 2:2 (ASV)

Set your affection.

Not "your affections." Tie them up into one bundle. Make one of them.

On things above, not on things on the earth.

You say that you were dead with Christ, and that you have risen with Christ. Live, then, the risen life, and not the life of those who have never undergone this matchless process. Live above.
