Colossians 3:1-11 If then you have been raised with Christ, seek the things that are above, where Christ is, seated at the right hand of God. Set your minds on things that are above, not on things that are on earth. For you have died, and your life is hid with Christ in God. When Christ who is our life appears, then you also will appear with him in glory. Put to death therefore what is earthly in you: fornication, impurity, passion, evil desire, and covetousness, which is idolatry. On account of these the wrath of God is coming.In these you once walked, when you lived in them. But now put them all away: anger, wrath, malice, slander, and foul talk from your mouth. Do not lie to one another, seeing that you have put off the old nature with its practices and have put on the new nature, which is being renewed in knowledge after the image of its creator. Here there cannot be Greek and Jew, circumcised and uncircumcised, barbarian, Scythian, slave, free man, but Christ is all, and in all.
We are encouraged by the Bible to set our minds on things above and not on things on earth. It does not mean you totally neglect your earthly duties. It means that you realize that you have to follow wisdom that come above, which is from God in heaven.
There is good reason to do so, as when Jesus shed his blood by dying on the cross, he took upon himself all of your sin. So when you believe in Jesus you believe that he came to take away your sins, your old life of sinfulness is taken away and you become a new creation. You may not be dead in the physical sense but in spirit you are dead to sin and there is a promise for you in Christ that you will be resurrected. You need to therefore live with that in mind.
You must there keep away from all sinfulness because sin was your old nature, so you can’t keep walking in it any more. You need to walk in the new nature, which the holiness which Christ has imparted to you. Therefore, you need to set your mind on Jesus above and not on things of this earth.
Here are a few scriptures you can reflect on:
Romans 6:13 Do not offer any part of yourself to sin as an instrument of wickedness, but rather offer yourselves to God as those who have been brought from death to life; and offer every part of yourself to him as an instrument of righteousness.
Romans 8:13 For if you live according to the flesh, you will die; but if by the Spirit you put to death the misdeeds of the body, you will live.
Galatians 5:19 The acts of the flesh are obvious: sexual immorality, impurity and debauchery
1 Corinthians 6:11 And that is what some of you were. But you were washed, you were sanctified, you were justified in the name of the Lord Jesus Christ and by the Spirit of our God.
2 Corinthians 5:14 For Christ’s love compels us, because we are convinced that one died for all, and therefore all died.
1 Peter 2:24 “He himself bore our sins” in his body on the cross, so that we might die to sins and live for righteousness; “by his wounds you have been healed.”
Isaiah 55:6-7 Seek the LORD while He may be found; Call upon Him while He is near. Let the wicked forsake his way And the unrighteous man his thoughts; And let him return to the LORD, And He will have compassion on him, And to our God, For He will abundantly pardon.
