Has someone ever promised you something that was important to you, only to either forget it or brake it for some reason? Many times people will off handedly promise something and they know they can't keep it. Maybe not realizing how important it was to you. People are so fallible. It's just the way we are made. You cannot be responsible for those around you and what they say they will do. You can only be responsible for your own promises. And God is a great promise keeper. Of course the promises of the bible are called covenants. And His promises can be written in stone.
Claim a scriptural promise as especially for you this day. Live confidently in its truth. Carry this tune as a reminder—Standing on the promises of Christ my King, thru eternal ages let His praises ring; glory in the highest I will shout and sing, standing on the promises of God.
