I cannot understand how anyone can claim to walk upright in fellowship with God perfectly without sinning. Do they know nothing of their own hearts? It seems to me that their knowledge of the character of sin and the exceeding sinfulness of sin and the utter deceitfulness of the human heart must be very shallow to think that sin only consists of those sins that are outwardly seen of others.
In my experience and I can confirm my experience that it is a true experience of a saved person by looking at the lives of some of the greatest Christians who have ever lived, in my experience I say, the closer a person gets to God, the more sins are revealed within their own hearts.
The utter infinite purity of God and His absolute righteousness is guaranteed to work in the human heart in this way. For someone to claim as some do, that God will keep them from any and every sin, is just shear delusion on their part. For one thing it is not true of the saints in the Bible. Take great king David, a man after God's own heart. God's words not mine. Here it is
And when he had removed him, he raised up unto them David to be their king; to whom also he gave testimony, and said, I have found David the son of Jesse, a man after mine own heart, which shall fulfil all my will.
Note the last phrase
which shall fulfil all my will
That was before David saw Bathsheba on the roof bathing. (did not God know that David was going to commit sin?) Suddenly he was met with the temptation that he must have her. And that is exactly what happened. Did the grace of God prevent him? No it didn't. And to make things worse, she became pregnant and that led him to commit another sin that was equivalent to murder. Again, did God prevent it? No He didn't.
But it goes further even than that. When Nathan the prophet came to him by the Spirit of God and reitterated the story of the other man's lamb. Remember that? You'll find the story in 2 Samuel 12.
And there came a traveller unto the rich man, and he spared to take of his own flock and of his own herd, to dress for the wayfaring man that was come unto him; but took the poor man's lamb, and dressed it for the man that was come to him.
and what was David's reaction to that?
And David's anger was greatly kindled against the man; and he said to Nathan, As the LORD liveth, the man that hath done this thing shall surely die: And he shall restore the lamb fourfold, because he did this thing, and because he had no pity.
Can you see this secret sin of David's? Pride and self righteousness, disguised as zeal for righteousness. And this made David blind to his own sins. Self righteousness always has that effect on the heart. It causes us to focus only those things that are obvious sins, but secretly cherish those sins that can be disguised as godliness and holiness and righteousness.
He was ready to pour out all his wrath upon that rich man who took the poor man's lamb. There he was no doubt, stalking around his throne and pinacle of personal piety judging others of their sins. No doubt he still thought he was a man after God's own heart. Yet he was so ignorant of the most glaring sins and most damnable sins known to human kind. Adulty and murder. And he was a child of God who had been blessed with every spritual blessing.
Nathan had to point his finger to him directly in order to open his blind eyes.
And Nathan said to David, Thou art the man.
And he spoke his message that God had given him.
Thus saith the LORD God of Israel, I anointed thee king over Israel, and I delivered thee out of the hand of Saul; And I gave thee thy master's house, and thy master's wives into thy bosom, and gave thee the house of Israel and of Judah; and if that had been too little, I would moreover have given unto thee such and such things.
Wherefore hast thou despised the commandment of the LORD, to do evil in his sight? thou hast killed Uriah the Hittite with the sword, and hast taken his wife to be thy wife, and hast slain him with the sword of the children of Ammon.
Now it is important to realise that David was not lost so that he went to hell. He was a saved man. Although God did judge him and because of his sin we are told
the sword shall never depart from thine house; because thou hast despised me, and hast taken the wife of Uriah the Hittite to be thy wife. Thus saith the LORD, Behold, I will raise up evil against thee out of thine own house, and I will take thy wives before thine eyes, and give them unto thy neighbour, and he shall lie with thy wives in the sight of this sun. For thou didst it secretly: but I will do this thing before all Israel, and before the sun.
We read of course that David repented of his sin. But his sin had forever changed the course of Israel's history.
But the point I want to emphasise here is that God did not prevent David from falling into sin. In fact everyone who reads their Bibles will have to acknowledge that God worked that terrible sin of David's into His own plan for the salvation of mankind. For from the union of Bathsheba and David came Solomon and he is in the genealogy of Jesus Christ. So of course is David for that matter.
So in the light of stories like that of David's sin is it Biblical to imagine that God will prevent anyone from falling into sin? I'm not suggesting that he will prevent people from falling. But what I am saying is, in the light of these things is it an absolute guarantee that God will not allow a Christian who is saved by the grace of God from falling into grievous sin?
And of course that begs the other question doesn't it? Is a person truly saved if they fall into grievous sin? Or is he lost the moment he sins.Then of course that begs yet another question doesn't it? If a person repents is he saved again? and of course that begs yet another question. Is a person lost again if he happens to sin again. What I am saying as well is can a man be saved one day and lost the next, just because he sins? Bearing in mind that sin does not only mean outward sins. But also those sins that we hold secretly in our hearts. For our Lord certainly saw these to be just as grievous as the outward sins. Perhaps even more so, for those secret sins of the heart include pride and envy and covetousness. In fact the sin of pride is generally thought to have been the cause of the downfall of Satan himself.
