What does the Bible say about Jesus' knowledge of our actions?

In Matthew 17:22-27, Jesus demonstrates His absolute knowledge by revealing details about a conversation Peter had even when He wasn't present. This affirms that nothing is hidden from Christ; He sees all and hears all. Hebrews 4:13 states, 'Everything is uncovered and laid bare before the eyes of Him to whom we must give account.' Believers are encouraged to conduct their lives with the understanding that they live in the sight of an omniscient Lord, who discerns our thoughts and motives.
