Christ has made a commitment to us. It's in the Bible, Romans 5:8, NIV. "God demonstrates His own love for us in this: While we were still sinners, Christ died for us."
Commitment is the beginning of trusting God. It's in the Bible, Psalm 37:5, TLB. "Commit everything you do to the Lord. Trust Him to help you do it and He will."
Our commitment to God must be consistent. It's in the Bible, Joshua 24:15, NIV. "But if serving the Lord seems undesirable to you, then choose for yourselves this day whom you will serve, whether the gods your forefathers served beyond the River, or the gods of the Amorites, in whose land you are living. But as for me and my household, we will serve the Lord."
