How do we know God will restore what was lost?

Throughout scripture, God repeatedly demonstrates His commitment to restoring His people. In the story of David, we see that despite his failures and the calamities he faced, God intervened and brought back all that was lost. This narrative in 1 Samuel 30 showcases that God is not only capable of restoring but also desires to do so for those whom He loves. His promises are woven into the fabric of the covenant, and they reflect His unchanging character as a God who seeks to recover His people from captivity and sin. We can cling to the hope that what was lost will be restored through faith in Him, as exemplified by David's own restoration.
