Set Your Affection On Things Above
"If ye then be risen with Christ, seek those things which are above, where Christ sitteth on the right hand of God [see What Is Jesus Christ Doing Right Now?]. Set your affection on things above, not on things on the earth. For ye are dead, and your life is hid with Christ in God. When Christ, Who is our life, shall appear, then shall ye also appear with Him in glory [see When Will You Be Judged?]." (Colossians 3:1-4 KJV)
"Set your affection on things above, not on things on the earth"
We are to "look to heaven," not because we are going there, but because "heaven" is coming here - when we are ready (see the Fact Finder question below).
"Mortify therefore your members which are upon the earth; fornication, uncleanness, inordinate affection, evil concupiscence, and covetousness, which is idolatry: For which things' sake the wrath of God cometh on the children of disobedience: In the which ye also walked some time, when ye lived in them.
But now ye also put off all these; anger, wrath, malice, blasphemy, filthy communication out of your mouth. Lie not one to another, seeing that ye have put off the old man with his deeds; And have put on the new man, which is renewed in knowledge after the image of him that created him: Where there is neither Greek nor Jew, circumcision nor uncircumcision, Barbarian, Scythian, bond nor free: but Christ is all, and in all." (Colossians 3:5-11 KJV)
Christ's people live according to Christ's example (see Jesus Christ and Christian Living).
"Put on therefore, as the elect of God, holy and beloved, bowels of mercies, kindness, humbleness of mind, meekness, longsuffering; Forbearing one another, and forgiving one another, if any man have a quarrel against any: even as Christ forgave you, so also do ye. And above all these things put on charity, which is the bond of perfectness.
And let the peace of God rule in your hearts, to the which also ye are called in one body; and be ye thankful. Let the word of Christ dwell in you richly in all wisdom; teaching and admonishing one another in psalms and hymns and spiritual songs, singing with grace in your hearts to The Lord. And whatsoever ye do in word or deed, do all in the Name of the Lord Jesus, giving thanks to God and the Father by Him." (Colossians 3:12-17 KJV)
