Everyone here misses our oldest child. They keep asking about him and how he is doing. (Our son returned to the States and he enlisted in the military.) One of the questions that they often ask is what would happen if our son decided he didn't want to be a soldier anymore. We tell them of the serious consequences of going AWOL (absent without leave). Our son made a commitment to the military for a certain amount of time, and he is obligated to fulfill that commitment.
Psalm 65:1 "Praise waiteth for thee, O God, in Sion: and unto thee shall the vow be performed."
The children of Israel, including David, also made a vow. Their vow was to praise the Lord for His goodness, blessings, and provision. This Psalm goes on to tell of how good God had been to them and how worthy He is of praise.
Do we have a commitment to praise the Lord? We should. He certainly is worthy. We should commit to praising Him every day, and we should take that vow seriously. Too often, though, we are AWOL in our praise. Circumstances are tough or we are tired or our day didn't go as expected, so we decide to skip praising the Lord. We take a day or two (or several) off from singing and shouting His praises. Isn't He still faithful and good even on days when we don't feel like praising Him?
One day last week, I saw a picture of my son online. His platoon was doing their physical training (PT) at 5:30 AM in the winter... outside. I bet he wasn't feeling like being a soldier at that time in the morning, but he manned up and broke a sweat with the rest of his platoon. My boy doesn't like to be cold, but he made a commitment and even at 5:30 in the morning he was determined to keep that commitment.
Some days, we just aren't going to feel like doing our PT (Praise and Thanksgiving). On those days we need to remind ourselves of our commitment and God's worthiness. We need to be sure we don't go AWOL on our worship and praise. God never goes AWOL on His grace and mercy!
