Psalms 119: 49-56 (49), is a great test for us to study. There David cries out “Lord remember what you promised me!” So David is calling upon God to remember for him what He promised him in His word.
We need that kind of relationship with God that we also will call our to God on that level and ask for help. As the text says, there is comfort waiting, but we with confidence can ask God our Father to help just us. God is willing, and has made us many great promises.
