Actually, I do not want to convey the impression I was into law keeping here since we live in New Covenantal times. Instead, I think we could use the OT law at times as a mirror that shows us what might be still wrong in our hearts and minds.
It appears to me that keeping the first commandment that says we should have no other gods beside our God tells us to somehow look through everything of which we think it is good around us as being blessing from God only. As soon as we cling to a person or a blessing they gave us as if he, she, or it represented the ultimate good that could make us happy or unhappy if we lost it, we have another god. I just thought I could share some thoughts on this topic from my fellow countryman Martin Luther with you on here.
