God is the only one we can truly put our trust in. When we put our faith in other people, they will eventually disappoint us. Psalm 146:3 says, Do not put your trust in princes, in human beings, who cannot save. Even the people closest to us; our spouses, parents, and close friends cannot be fully trusted to fulfill our happiness. Only God can truly be trusted with our hearts. When we trust in Him, He protects us from others potentially hurting us and gives us the joy we need.
