How do we know our hearts and words are acceptable to God?

Knowing whether our hearts and words are acceptable unto God is not something we can ascertain by our own merit but requires the grace of God. David's prayer in Psalm 19:14 serves as a reminder for believers to earnestly seek God’s approval in their communications. We are assured that with attentive prayer and reliance on His strength, our hearts can be aligned to meditate on good matters, as noted in Psalms 45:1 and 5:1. Such an approach acknowledges our reliance on God’s grace to overcome our sinful inclinations and strive for words and meditations that glorify Him.
