Taste and see that the LORD is good; blessed is the one who takes refuge in Him. — Psalm 34:8
What the Psalmist is inviting us to do is, experience God first-hand. David experienced God’s faithfulness throughout his life. God was his deliverer when he was being chased by his enemies, He was his Protector when he was in danger, He was his Provider in times of need. Above all, he knew God to be merciful when he fell from grace and sinned against God. The Psalmist wants us to know, there is a blessing for those who take refuge in God.
This God will take care of us until the end and give us eternal life when we put our faith in His Son Jesus Christ.
