Moses had been teaching the people of Israel and we read in Deuteronomy now calls for them to make a decision. Here are the words:
"See, I have set before you today life and prosperity, death and adversity. If you obey the commandments of the Lord your God that I am commanding you today, by loving he Lord your God, walking in his ways, and observing his commandments, decrees, and ordinances, then you shall live and become numerous, and Lord your God will bless you in the land that you are entering to possess. But if your heart turns away and you do not hear, but are led astray to bow down to other gods and serve them, I declare to you today that you shall perish; you shall not live long in the land that you are crossing the Jordan to enter and possess." Deuteronomy 30:15-18
After speaking these words, Moses advises them to "choose life." The choice was theirs and the choice is ours. I believe that each day we do make decisions either in line with God's ways or against them. We need to continually be attentive to our way of living.
The appointed psalm for this day which is Psalm 1 states that happiness is found by delighting in the law of the Lord and meditating on it day and night. There would be no forgetting and there would be a constant reminder of what God desires for our living by such meditation.
We would do well to work to have our own lives centered on God. We need to examine how we are loving God and loving our neighbor, which is what all the law really means. I would have you focus on these words from Deuteronomy and also read through Psalm 1 (it's short) in preparation for Sunday's worship.
