Because we have been saved through Christ and brought into God’s family, Peter calls us to live as obedient children who imitate our holy Father. No longer “sons of disobedience,” we now show our identity as His children by obeying His Word, turning away from the sinful desires that once ruled us, and walking in holiness. This means guarding against anything that stirs up lusts of the flesh, putting on Christ instead of making room for sin, and treasuring God’s Word so we may know His ways. Just as athletes or artists study their masters, we fix our eyes on the Lord, who is perfectly holy and radiant in light, so that our lives reflect His character. This lesson teaches us to imitate our holy Father.
