Did you ever get in trouble as a kid? Do you remember how you felt when you were scolded? I do. When my parents scolded me, it normally took me a few days to really feel like I could comfortably approach them again. Why? I felt distanced from them because they scolded me. Similarly, when God scolds us, we feel distanced from Him. We don't want to approach Him, but do you remember what He says in Proverbs 3:11-12? "My son, despise not the chastening of the LORD; neither be weary of his correction: For whom the LORD loveth he correcteth."
Many times when we mess up, we don't want to approach God. James says, "Draw nigh to God, and he will draw nigh to you" (4:8). Then, this is interesting, the very next sentence states, "Cleanse your hands ye sinners; and purify your hearts, ye double-minded. Be afflicted, and mourn, and weep: let your laughter be turned to mourning, and your joy to heaviness," and "Humble yourselves in the sight of the Lord, and he shall lift you up." So, you don't want to approach God because you have sinned, but that's the time when you need to approach and repent when you come.
Listen, the book of Hebrews 12 tells us:
12 Wherefore lift up the hands which hang down, and the feeble knees; 13 And make straight paths for your feet, lest that which is lame be turned out of the way; but let it rather be healed. 15 Looking diligently lest an y man fail of the grace of God; lest any root of bitterness springing up trouble you, and thereby many be defiled; 16 Lest there be any fornicator, or profane person, as Esau, who for one morsel of meat sold his birthright. 17 For ye know how that afterward, when he would have inherited the blessing, he was rejected: for he found no place of repentance, though he sought it carefully with tears.
You see, if you don't approach God when you have failed Him, you can become bitter (v. 15). But, instead of becoming bitter, He invites you to come to Him and be healed. "Lest that which is lame [meaning you have to yourself now an injury because you fell] be turned out of the way" (v. 13). In other words, God refused you because you who are now lame didn't come for your healing - so now, you fail of the grace of God. He made it available to you, but you failed to receive it and continue on in your sin. Doing this, my friend, makes you insult the Spirit of grace. You have counted God's grace not sufficient to help you overcome your sin.
The Bible says, If we sin, not when we sin, but if we sin. Hear what the Apostle John wrote, "My little children, these things write I unto you, that ye sin not. And if any man sin, we have an advocate with the Father, Jesus Christ the righteous" (1 John 2:1).
God has made His grace available to you NOW if you are struggling in sin. Instead of reaching out and taking hold of that grace like you should, you have been taught to understand grace to mean that you can still live in sin and God's grace will take care of you. If you think this, you have been sincerely deceived and poorly taught.
Instead of saying, Well we are all sinners and no one can live a perfect life, why not believe God's word that He is able to help you overcome that sin. Listen, if you say you believe in God and the gospel you believe does not have the power to deliver you from the sin you are involved in, then the gospel you believe has no teeth and Christ has died in vain. But, Christ did not die in vain and as He conquered sin and death, you can too - through Him.
When we mess up and commit a sin, God is calling us to, Come here. He says, "Let us therefore come boldly unto the throne of grace, that we may obtain mercy, and find grace to help in time of need" (Hebrews 4:16). You see, God has the grace to give you when you are weak and help you overcome that sin. He said, "My grace is sufficient for thee: for my strength is made perfect in weakness" (2 Cor. 12:9).
If you say, I can continue in my sin because God's grace will take care of me, you have understood the Scriptures wrongly and show that you are going to try to abuse God's grace. God says,
If we decide to go on sinning after we have learned the truth, there is no longer any sacrifice for sins. There is nothing but fear in waiting for the judgment and the terrible fire that will destroy all those who live against God...So what do you think should be done to those...who insult the Spirit of God's grace? (Hebrews 10:26-29).
My friend, He has given you grace so that you can use it to start walking right with Him again. This is a marvelous gift! So Come!
He also says, "If any man draw back, my soul shall have no pleasure in him" (Heb 10:38). You insult His Spirit of grace if you draw back. Instead, use the grace He gives as a stepping stone to get closer to Him.
