Charles Spurgeon Commentary Colossians 3:1-2

"If then ye were raised together with Christ, seek the things that are above, where Christ is, seated on the right hand of God. Set your mind on the things that are above, not on the things that are upon the earth." — Colossians 3:1-2 (ASV)

If you then are risen with Christ, seek those things which are above, where Christ sits on the right hand of God. Set your affection on things above, not on things on the earth.

This is the best proof that we are really "risen with Christ," that we set our affection on things above.
