This is another joint article Susanne Schuberth* and I wrote together with the leading of the Holy Spirit.
Jesus was without sin because He only did what He saw His Father doing and He only spoke His words. This is why Paul could say that nothing of itself is sin, but only that which is done without faith… which is not doing what our Daddy in Heaven shows us to do and say. Faith is not law keeping. Faith is obeying the Spirit and the wind of the Spirit blows where no man expects it to. We must be free to follow the leading of the Spirit if we are to walk by faith. This is why Peter was sinning when he refused to eat with Gentiles, though the law forbade him to do so, but the Spirit of the NEW covenant often surpasses the law. The apostle Paul told us the following,
“I know and am persuaded in the Lord Jesus that nothing is unclean in itself, but it is unclean for anyone who thinks it unclean.” (Rom 14:14 ESV)
“To the pure, all things are pure, but to the defiled and unbelieving, nothing is pure; but both their minds and their consciences are defiled.” (Titus 1:15 ESV)
So, we see in the New Testament that nothing of itself is unclean. We need to only follow the leading of the Spirit in ALL things we do and say. But herein lies the danger as well… If we are not walking in faith and are not in tune with the Spirit, we can fall into delusions for our adversary is good at getting us to believe a lie. It is not by law keeping that we are made safe, but rather by living by EVERY word that proceeds from the mouth of God and not living by our fleshly desires and the lies of the serpent. Remember that the devil used scripture to tempt Jesus to sin!
We also know that if we are acting out of unselfish love in whatever we do, we are fulfilling the O.T. law AND the law of Christ.
For all the law is fulfilled in one word, even in this; You shall love your neighbor as yourself. (Galatians 5:14, KJ2000)
For what the law could not do, in that it was weak through the flesh, God sending his own Son in the likeness of sinful flesh, and for sin, condemned sin in the flesh: That the righteousness of the law might be fulfilled in us, who walk not after the flesh, but after the Spirit. (Romans 8:3-4, KJ2000)
But how do we know if we just now are walking by faith – or not? The Bible tells us,
“You keep him in perfect peace whose mind is stayed on you, because he trusts in you.” (Isaiah 26:3 ESV)
We can be sure if we are enwrapped in His peace right now, we are in His will, we are walking by faith and there is no sin so that there would be an open door for Satan to make us fear, worry, or a possibility to deceive or delude us. This was summed up in what Paul wrote to the Philippians…
Rejoice in the Lord always: and again I say, Rejoice. Let your moderation be known unto all men. The Lord is at hand. Be anxious for nothing; but in everything by prayer and supplication with thanksgiving let your requests be made known unto God. And the peace of God, which passes all understanding, shall keep your hearts and minds through Christ Jesus. Finally, brethren, whatsoever things are true, whatsoever things are honest, whatsoever things are just, whatsoever things are pure, whatsoever things are lovely, whatsoever things are of good report; if there be any virtue, and if there be any praise, think on these things.” (Philippians 4:4-8, KJ2000)
So, back to our question, “How does God define sin?” Paul wrote “For all have sinned, and come short of the glory of God.” (Romans 3:23, KJ2000) Any time we are falling short of the glory of God we are in sin… That is any time our lives and our words are not glorifying God and His will for us, we are sinning. We are called to walk as Jesus walked on this earth in total obedience to the Father with lives that glorify Him. “Father, continue to mature us in your Spirit so that we might live lives that only glorify you. Amen.”
