Have you ever made a promise to God? Did you keep it? I remember when I was 12-years-old and a friend of mine offered me some chewing tobacco. I knew better than to try it, but I tried it anyway. As gross as this sounds, he also encouraged me and another friend of mine to swallow the saliva that was generated while we were chewing it, instead of spitting it out. I took his advice and did that. Within minutes, I went from feeling healthy and fine to feeling like I had the worst case of the flu. My stomach was upset and my head was pounding. It felt like the sick feeling would never go away.
So I made a promise to God. If He helped me to feel better, I promised to never chew tobacco again. In an hour or so, I started to feel a little better, but instead of keeping my promise, I started to use tobacco in just about every form it came in for the next two years. For me, it was very difficult to stop, and in the process I made many promises to God that I broke.
Throughout the Scriptures, we're told of various "covenants" or "agreements" God has made with His people. Interestingly, He always keeps His end of the agreement while His people have a consistent tendency of breaking theirs. But one of the covenants God initiated, the New Covenant, offers us the opportunity to have our sin permanently forgiven and our fellowship with God restored forever. This portion of Jeremiah's book speaks of the New Covenant.
