What does Psalm 10:11 mean?

Those who reject God's authority often waver in how they express that rebellion. In some cases, they deny that God exists at all (Psalm 10:4). Those same people, however, often criticize or misrepresent God to make Him fit their preferences. In that same way, the same wicked man who refuses to believe God exists now claims God has forgotten his evil crimes against the helpless. He even supposes God has hidden His face and will never see the evil the wicked man commits.

Of course, anyone who thinks this way is terribly wrong (Revelation 20:11–15). Hebrews 4:13 exclaims, "And no creature is hidden from his sight, but all are naked and exposed to the eyes of him to whom we must give account." After Hagar fled from Abram's home because Sarai, Abram's wife, had dealt harshly with her, she rested by a spring of water in the wilderness. The angel of the Lord found her there and commanded her to return to Sarai and submit to her. He assured her she would bear a son who would become the father of a vast number of people. In response, Hagar "called the name of the LORD who spoke to her, 'You are a God of seeing,' for she said, 'Truly here I have seen him who looks after me'" (Genesis 16:13).
