22 Since you have purified your souls in obeying the truth through the Spirit in sincere love of the brethren, love one another fervently with a pure heart, 23 having been born again, not of corruptible seed but incorruptible, through the word of God which lives and abides forever, 24 because “All flesh is as grass, and all the glory of man as the flower of the grass. The grass withers, and its flower falls away, 25 But the word of the Lord endures forever.” Now this is the word which by the gospel was preached to you. (1 Peter 1:22–25, NKJV)
This passage identifies the word of God and describes what it does. First, the word of God is “the truth” (v. 22). The word of God is not a truth among many other truths. It is the truth, it is exclusive, accurate and reliable because is the word of God, not the word of men (1 Thessalonians 2:13). The truth of God purifies the soul when it is obeyed (v. 22; Hebrews 5:9). Our souls cannot be purified unless we obey the truth. Next, the word of God is the seed that produces the new birth (v. 23). The sinner is “born again” when this seed is planted in the heart and obeyed from the heart (Luke 8:11, 15). Those who believe sinners are born again without obedience must ignore this verse (John 3:3, 5). The word of God is powerful, incorruptible and “endures forever” (v. 23, 25). The first-century gospel will do its work in this century. We must receive and obey the truth – the incorruptible word – to be purified of sins and to truly love one another (John 8:31-32; 13:34-35).
