Is Imperfection a license to sin?

Romans 6
1 What shall we say then? Shall we continue in sin, that grace may abound?
2 God forbid. How shall we, that are dead to sin, live any longer therein?

Galations 5
13 For, brethren, ye have been called unto liberty; only use not liberty for an occasion to the flesh, but by love serve one another.
14 For all the law is fulfilled in one word, even in this; Thou shalt love thy neighbour as thyself.
15 But if ye bite and devour one another, take heed that ye be not consumed one of another.
16 This I say then, Walk in the Spirit, and ye shall not fulfil the lust of the flesh.

Luke 6:42
“Either how canst thou say to thy brother, Brother, let me pull out the mote that is in thine eye, when thou thyself beholdest not the beam that is in thine own eye? Thou hypocrite, cast out first the beam out of thine own eye, and then shalt thou see clearly to pull out the mote that is in thy brother's eye.”

Today I saw a post on Facebook about a woman who killed her two daughters for reasons that she believed were right, but was grossly mislead in what Christianity was about.

Someone who did understand commented by calling the woman an ungodly name, then explained that the woman was no Christian and offered an ungodly means to rid of her.

I was taken aback. As Christians, yes, it is right for us to be righteously angry at the ignorance of those who claim to follow God, and even more so when they do ungodly things in His name. But, we, as Christians need to be careful not to fall into the same category by reacting in ungodly ways to ungodly people.

The fact that we are not perfect doesn't give us a license to sin. We should, instead, strive to better ourselves. Yes, we all slip. I still struggle with the old me sometimes. I check myself as soon as I slip and I ask for forgiveness, and I strive not to slip again. If we are not aiming to better ourselves, then how are we to expect better of others?

As Christians, the world is watching us. It is who we show the world we are after salvation that wins others to Christ. We cannot demand that others act in godly ways, nor can we point out others ungodly behavior while refusing to fix our own, or acknowledge our own sin in the process.
