“Thou shalt also consider in thine heart, that, as a man chasteneth his son, so the LORD thy God chasteneth thee. Therefore thou shalt keep the commandments of the LORD thy God, to walk in His ways, and to fear Him.” Deuteronomy 8:5-6 (KJV)
The book of Deuteronomy was written shortly before Moses would go upon the mount to die; and shortly before the children of Israel would cross into the Promised Land. It is basically a book, not of new laws, but a reminder of the past forty years; and their journey in the wilderness.
God’s heart for His people is that they walk with Him, that they love Him. It has greatly grieved the heart of God when He sees His people violate His standards of holiness and righteousness.
When God’s people love Him they will walk with Him, and fear Him. We need not, as Christians, struggle with the matter of obedience to the law. It has been written in our hearts, because of the work of Jesus Christ. The Christians greatest desire is to love God, obey Him, and walk with Him. When we fail, and our heart reminds us of our failure; and many times before our hearts remind us; the LORD disciplines those who sin.
The writer of Hebrews addresses this matter of discipline or chastening;
“And ye have forgotten the exhortation which speaketh unto you as unto children, My son, despise not thou the chastening of the Lord, nor faint when thou art rebuked of Him: for whom the Lord loveth He chasteneth, and scourgeth every son whom He receiveth. If ye endure chastening, God dealeth with you as with sons; for what son is he whom the father chasteneth not? But if ye be without chastisement, whereof all are partakers, then are ye bastards, and not sons.” Hebrews 12:5-8
We ought to rejoice in the fact that we are chastened. It is one evidence that we are God’s child. Like the presence of the Spirit within the life of the Christian (Romans 8:9); so the presence of the chastening of the Lord is evidence of your faith in God.
The heart that loves God does not seek to excuse sin, personal sin, nor to condemn others who may oppose their sin; but rather submits to the word, way and law of God. That heart that loves God confesses their sin, repents of the sin, and hates their sin.
Listen to the law of God written in your heart, and obey Him. Not to gain His favor, but because you already have His favor through grace, by His Son Jesus Christ.
