“Being born again, not of corruptible seed, but of incorruptible, by the Word of God” (I Peter 1:23)
Where did Peter learn about “being born again?” Where did he learn of the incorruptible seed? The first Lesson from the Lord in our text could have taken place when the Savior talked to Nicodemus and told him, “Ye must be born again” (John 3:7). The second lesson was perhaps learned when the Lord said, “Behold a Sower went forth to sow… He that received seed into the good ground is he that heareth the Word and understandeth it, which also beareth fruit…” (Matthew 13:3-23). There is the principle of life within the seed.
This Seed, the Word, was implanted within our hearts and germinated, bringing forth fruit. It is because of this implanted Word and the indwelling of the Holy Spirit that the believer has been changed and has the desire and power to live for God.
Because of this new birth, by the Word of God, the believer has a new set of desires. The Bible becomes a new Book. We are therefore told to desire earnestly the sincere milk of the Word that we may grow thereby – to continue desiring that by which we were delivered.
