How does God approve those who are His?

God's approval is not given based on human merit but is fully dependent on faith in Christ. As indicated in 2 Corinthians 10:18, it is not those who commend themselves who are approved, but those whom the Lord commends. This aligns with the concept of being 'approved in Christ' as articulated in Romans 16:10. True approval by God is manifested through resting solely in Christ’s finished work rather than any personal accomplishments. It emphasizes that only in Christ is there hope for salvation and acceptance before God.
