Lamentations 3:23b says, 'Great is Your faithfulness.' The chorus of a well-known hymn on God's faithfulness (Hymns, #19) says, ''Great is Thy faithfulness!' 'Great is Thy faithfulness!' / Morning by morning new mercies I see / All I have needed Thy hand has provided-/ 'Great is Thy faithfulness,' Lord, unto me!' We may understand what the Bible says and what this hymn says about God's faithfulness either in a natural way or in a spiritual way.
Although we are unfaithful, God is faithful.
