4 For it is impossible for those who were once enlightened, and have tasted the heavenly gift, and have become partakers of the Holy Spirit, 5 and have tasted the good word of God and the powers of the age to come, 6 if they fall away, to renew them again to repentance, since they crucify again for themselves the Son of God, and put Him to an open shame. (Hebrews 6:4–6, NKJV)
Verse 6 gives the reason for the impossibility of renewal to repentance if Christians fall away. When fallen Christians continue to practice their sins, they forfeit the power to renew their faith. It is impossible to be renewed spiritually while continuing to sin. They are crucifying the Son of God by their willful transgressions, openly shaming Him by their return to and continuance in sin (Heb. 10:26-31). Indulging in sin instead of resisting it hardens hearts that were once enlightened, enlivened, and edified by God’s word and its promised hope. Therefore, we are warned not to let sin have a place in our hearts and lives (Heb. 3:12-13). Yes, Christians can fall away and be lost (2 Pet. 2:20-22; Gal. 5:4). And yes, fallen saints can be restored to Christ, but only by strictly putting away the sins that have prevented their repentant return to the Lord. Willful sin must cease for divine mercy to take its place (Lk. 15:17-24).
And let the peace of God rule in your hearts, to which also you were called in one body; and be thankful. (Colossians 3:15, NKJV)
The gospel calls us to peace with God and with others. Sin introduced conflict between man and God, producing spiritual death and consequentially, physical death (Gen. 2:17; 3:19; Rom. 5:12; 6:23). The angelic announcement at Christ’s birth (“Glory to God in the highest, and on earth peace, goodwill toward men!”) praised God for His goodwill toward humanity that brought peace between Himself and sinners through His Son (Lk. 2:14; Tit. 3:4-5). Jesus Christ “is our peace” (first with God, then with other sinners) – “For He Himself is our peace, who has made both one…” (Eph. 2:14). Being reconciled to God “in one body through the cross, thereby putting to death the enmity,” hostility with God is removed and replaced with harmonious tranquility “in one body” (the church). That is the peace the angels announced. That is the peace Christ’s death accomplished. That peace must now rule (govern) our hearts. Being at peace with God, we can successfully strive to “live peaceably with all men” (Rom. 12:18). Until then, sin rules the heart, infusing our marriages, families, nations, and the church with its selfishness, confusion, and every evil thing (Jas. 3:14-16). By contrast, “the wisdom that is from above is first pure, then peaceable, gentle, willing to yield, full of mercy and good fruits, without partiality and without hypocrisy” (Jas. 3:17). Thank God for His peace! Without Him, peace is unattainable.
30 “As for you, son of man, the children of your people are talking about you beside the walls and in the doors of the houses; and they speak to one another, everyone saying to his brother, ‘Please come and hear what the word is that comes from the Lord.’ 31 So they come to you as people do, they sit before you as My people, and they hear your words, but they do not do them; for with their mouth they show much love, but their hearts pursue their own gain.” (Ezekiel 33:30–31, NKJV)
Everybody wanted to hear the prophet! Yet, God was thoroughly disgusted with His people. They were comfortable with their outward display of being interested in God, even while their hearts were far from Him. They were excited to hear what the prophet said “from the Lord”, but they were not at all interested in doing what He said. Their words talked of love for God, but their hearts were full of selfishness – and their lives showed it. Let us learn from them and avoid being like them. We must completely devote our hearts to loving God. Only then will we conform our words and our actions to God’s word, and by doing so, come into His presence.
