Peter knew that the Gentiles were no longer to be considered unclean (Acts 10:9-16), and he demonstrated this by eating with them. However, when some prominent Jews arrived, Peter “withdrew and separated himself, fearing them which were of the circumcision.” He knew better but allowed fear to cause him to rebel against the clear teachings of the Lord. As such, Peter “was to be blamed” (Galatians 2:11), and Paul had to rebuke him. It is one thing for a man to sin against the Lord through ignorance, but Peter knowingly, purposely, and openly violated God’s word. In like manner, believers today must bear the blame and the shame when they sin against the clear teachings of scripture.
Our passage tells us that God is not in all the thoughts of the wicked (Psalm 10:4). It also points out that the thoughts of the wicked “are thoughts of iniquity” (Isaiah 59:7). Obviously, the wicked despise the Lord in their thoughts, but the Lord also despises the thoughts of the wicked. This is why we are told that “The thoughts of the wicked are an abomination to the LORD” (Proverbs 15:26). King David, whom God called “a man after mine own heart” (Acts 13:22), added that the thoughts of the wicked were against him for evil (Psalm 56:5). These wicked thoughts are based upon pride (Psalm 10:4). Conversely, a man yielded to the Lord desires to bring “into captivity every thought to the obedience of Christ” (2 Corinthians 10:5).
