Avoid ugliness by avoiding sinful urges
A person who doesn't learn to control his habits but persists with irresponsible and harmful behaviours is destined to wear the mandatory attire of the convicted felon. Society has little tolerance for the drunkard, the theif or the adulterer. Despite the clear warnings about such things, many people still end up being incarcerated for their acts of selfishness, foolishness or criminal intent, not to mention for their greed or anger in moments of stupidity. Somewhat more hidden, but equally unbecoming for the Christian, are the more subtle urges that could cause us to harbor feelings of envy, or revenge, or pride or lust. The New Testament makes it clear that behaviour in any such manner is totally inappropriate for God's people, and mentions many of the "bad looks" that are the ugly side of sin.
"The acts of the flesh are obvious: sexual immortality, impurity and debauchery; idolatry and witchcraft; hatred, discord, jealousy, fits or rage, selfish ambition, dissentions, factions and envy: drunkenness, orgies and the like. I warn you as I did before, that those who live like this will not inherit the Kingdom of God. But the fruit of the Spirit is love, joy, peace, forbearance, kindness, goodness, faithfulness, gentleness and self-control. Against such things there is no law. Those who belong to Christ Jesus have crucified the flesh with its passions and desires. Since we live by the Spirit, let us keep in step with the Spirit. Let us not become conceited, provoking and envying each other." (Galatians 5:20-26 NIV)
"As for you, you were dead in your transgressions and sins, in which you used to live when you followed the ways of this world and the ruler of the Kingdom of the air, the spirit who is now at work in those who are disobedient. All of us also lived among them at one time, gratifying the cravings of our flesh and following its desires and thoughts. Like the rest, we were by nature deserving of wrath. But because of His great love for us, God, who is rich in mercy, made us alive with Christ even when we were dead in transgressions - it is by grace you have been saved." (Ephesians 2:1-5 NIV) Also you will find similar in Ephesians 4:17-32)
Believers who choose to "clothe" themselves with the same qualities of benevolence as Jesus did, will one day receive a garment of light and immortality. "And just as we have been borne the likeness of the earthly man, so shall we bear the likeness of the man from heaven." (1 Corinthians 15:49 NIV) Paul goes on to say "this perishable nature must put on the imperishable" and gives Christians the magnificent promise about the change going on inside of us, saying we "are being transformed into His likeness with ever-increasing glory". (2 Corinthians 3:18 NIV) Receiving the Holy Spirit is like a deposit guaranteeing our inheritance, and the cloak of glory is a component of this gift to us, that we receive as a replica of Christ's most glorious splendour, honor and majesty.
