It's healthy for us to lose once in awhile. It's good to get our knees scraped or our noses bloodied every so often. It helps us remember that there's an enemy out there who wants to keep us and our family and our friends out of heaven. And to Thy tabernacles. When it looks very dark, when the bad guys seem to be winning, I need the Lord's light and His truth.
Light dispels darkness and exposes the traps placed by the enemy.
God's light and truth help us find the way to a much better place. It says we will go to the altar of God, experience the joy of His presence, and spend time playing the harp and praising God. But that's not what it says here. Not just my contentment, or my boredom, or my so-so. Now the writer gives us some insight into his personal feelings.
