Forgive.

 We are told this by our Savior-

Mat 5:21 Ye have heard that it was said by them of old time, Thou shalt not kill; and whosoever shall kill shall be in danger of the judgment:

Mat 5:22 But I say unto you, That whosoever is angry with his brother without a cause shall be in danger of the judgment

Even anger brings on reason for judgment, just as killing. We are guilty on so many levels, and Satan will use all sorts of things to get us to sin in our hearts. Satan doesn't care if we put on an outward show of sinlessness, as long as our hearts hold sin. And as long as our hearts hold sin, we are far from sinlessness even if we tell ourselves we are just because we don't commit the acts we might happen to think on. Our thoughts, our secrets, will be brought into judgment. We are all worthy of death even by our thoughts, we are all sinners, unable to cast that first stone. We must seek forgiveness and we must forgive all the time!

Rom_2:16 In the day when God shall judge the secrets of men by Jesus Christ according to my gospel.

1Co 4:5 Therefore judge nothing before the time, until the Lord come, who both will bring to light the hidden things of darkness, and will make manifest the counsels of the hearts: and then shall every man have praise of God.

Eph 4:32 And be ye kind one to another, tenderhearted, forgiving one another, even as God for Christ's sake hath forgiven you.
