"I will bless the LORD at all times: his praise shall continually be in my mouth." (Psalm 34: 1)
David sang this psalm in the Cave of Adullam ("rest" in Hebrew)
He was hiding from King Saul, the monarch who had lost his mind, who was hunting David, even though he was himself sore hunted by an evil spirit.
David did not have strong friends, counselors, or any kind of support with him.
"And every one that was in distress, and every one that was in debt, and every one that was discontented, gathered themselves unto him; and he became a captain over them: and there were with him about four hundred men." (1 Samuel 22: 2)
One could say that David was a sore loser surrounded by losers.
David had been anointed king of Israel to replace Saul, and the people of Israel celebrated his slaying tens of thousands compared to Saul's thousands.
Yet for all the fame, for all the glory, he was on the run, and he had even pretended to be crazy before the king of the Philistines to protect himself.
He was down, but not out, He was perplexed, but not crushed.
How can this be, and how can this be so for us?
We must never judge God's love for us based on our circumstances, never!
We judge God's love for us in that He has anointed us with His Holy Spirit, that we have received the Spirit of Adoption (Romans 8: 15)
We do not judge God for this evil world, for in Christ we have overcome the world (John 16: 33), and He is greater than anything we may face (1 John 5: 4-5)
Praise Him for His mercy, His grace which endures forever. Recall that Jesus became the biggest loser at the Cross that you may be a winner in Him (2 Corinthians 5: 17-21)
