They who defend their sins, will see in the great day whether their sins can defend them.

1Jn 1:4  And these things write we unto you, that your joy may be full.

1Jn 1:5  This then is the message which we have heard of him, and declare unto you, that God is light, and in him is no darkness at all.

1Jn 1:6  If we say that we have fellowship with him, and walk in darkness, we lie, and do not the truth:

1Jn 1:7  But if we walk in the light, as he is in the light, we have fellowship one with another, and the blood of Jesus Christ his Son cleanseth us from all sin.

1Jn 1:8  If we say that we have no sin, we deceive ourselves, and the truth is not in us.

1Jn 1:9  If we confess our sins, he is faithful and just to forgive us our sins, and to cleanse us from all unrighteousness.

1Jn 1:10  If we say that we have not sinned, we make him a liar, and his word is not in us.

The title is a profound thought, think on just the title and we will move on.

This is a well-known part of the word why? We all sin, that is why.

 It is something we cannot escape on this life, sin, mistakes, bad decisions, and such things that are not pleasing to the lord. You know what they are, the holy spirit has already convicted you, you work out your own salvation with fear and trembling , as I do my Christian walk.

People love to find someone, anyone to blame, they did it to King David at Ziglag.

 Man is like that, whom can I blame. We should first blame ourselves for thinking who we can blame, think of that.

 Just looking for someone to blame is ungodly, so why do so many do it, esp. in marriage, we can not at times face the truth, maybe it was me, or you, maybe we are the one at fault.

Faultfinders are everywhere. Esp. on the net, as they can say whatever they want and not eye to eye, this is a coward and not a person of God.

 Paul confronted Peter face to face, not behind his back.
 Once you go public you pay a certain price that’s the way it works, everyone has a difference of opinion, a different view, a different take, but most forget we also have different gifts and callings, why would I want to be like MR X when I am MR L.

 We are never to compare ourselves by ourselves and standards, as Paul said to the Corinthian church, do compare others by yourself, this is wrong we are all different we all have different callings, so do not judge a person because he is not in your calling, embrace the difference, as the parts make the whole of the spiritual body.

Sin, the short verse in Romans says what sin is, ‘whatsoever is not of faith is sin’, there is more to it, but that is sin concisely.

The word teaches us, do not try and take the speck out of your brothers eye, until you take the log out of your eye, than you can go and try and reason, minister , and teach the one with a speak, but our logs can be so big they blind us and make us an island to ourselves we become segregated by our own vision, this I have seen over and over. And have been guilty of in my own life at times, esp. when I was a young preacher.

In this text, it is the same we are talking about light, truth and forgiveness when we sin.

Note : To do nothing and only criticize others who are doing, is a great sin and is one of pride, never be a do nothing Christian as they are the worst arm chair ministers and never enter in the game, they call fowl and nothing else, do nothing else, have no walk, do nothings, these who do, make many mistakes, think of Babe Ruth, and his home run record, and look at his strike out record, if anyone one had just his strike out record they would be kicked off the team, but in all his strike outs he made many home runs, so be a do something Christian and not an arm chair Christian.

Some denominations, churches believe once you are saved your all set, this clearly teaches otherwise. The word speaks the truth as our text shows.
JFB commentary puts this well:

that we have no sin — “HAVE,” not “have had,” must refer not to the past sinful life while unconverted, but to the present state wherein believers have sin even still. Observe, “sin” is in the singular; “(confess our) sins” (1Jo_1:9) in the plural. Sin refers to the corruption of the old man still present in us, and the stain created by the actual sins flowing from that old nature in us. To confess our need of cleansing from present sin is essential to “walking in the light”; so far is the presence of some sin incompatible with our in the main “walking in light.” But the believer hates, confesses, and longs to be delivered from all sin, which is darkness. “They who defend their sins, will see in the great day whether their sins can defend them.”

We are sinners saved by grace, we must deal with sin, it cannot go, or it will grow, and you could lose your salvation, your Christ likeness, and your usefulness to the kingdom of God.

It is a hard thing, the flesh, the devil, we battle everyday one or the other, the good news is we have forgiveness, if we repent, and as the text says in the intro to this epistle let it ring out today in your heart.

1Jn 1:4  And these things write we unto you, that your joy may be full.

The epistle, as most epistles do contain hope and conviction, but notice what the Apostle of love says, I am going to teach a lot of truth in this letter but first know you’re being told all, so your joy may be full.

 Un-confessed sin, gossip, measuring yourself against others, back biting, sins of the mouth and thoughts, take away this full joy, repentance and obedience restore it, so let us receive the word in its fullness and receive the light where there is no darkness, our lord Jesus Christ and walk in his full joy today.
