According to the scribal superscription, Psalm 34 is believed to have been written when David - in attempting to avoid King Saul - fled to Gath and then pretended madness before the Philistine ruler Abimelech so he could escape him also (1 Sam. 21:12-22:1). In the eighth verse of this acrostic psalm, David exclaims "Oh, taste and see that the Lord is good; blessed is the man who trusts in Him!"
It is true that: because God is spirit (John 4:24), our five senses are unable to perceive Him directly. However, it is also true that our five senses are capable of witnessing the intentional and infallible proofs of His existence - the heavens declare His glory (Ps. 19:1), His eternal power and Godhead are clearly seen in the physical universe (Rom. 1:20). According to this psalm, our senses are capable of tasting and seeing Jehovah's goodness.
You can taste and see God's goodness in the rain that falls from heaven and the fruitful harvests the rain and soil combine to produce (Acts 14:17). Seeing a tree laden with ripe fruit in the fall or eating a luscious peach, pear, apple, or plum picked from its branches are occasions in which you can taste and see Jehovah's goodness. Though seed time and harvest are among the universal laws of nature since the Flood (Gen. 8:22), these immutable seasons were graciously given by God. At every harvest and with every day's bread, blessed is he who can taste and see Jehovah's goodness.
You can taste and see God's goodness in the Bible you read every day. Not only are the Holy Scriptures infallible, tangible proof of the Holy Spirit's existence, they are also evidence of God's goodness and grace. Their instructions to deny ungodliness and worldly lusts and live soberly, righteously, and godly in this present world are visible proof of God's grace which brings salvation to all (Titus 2:11-12).
The grace of God is not some nebulous collection of goosebumps, forever swirling in a pie-in-thesky state. It is a genuine spiritual reality which has provided all the spiritual instructions necessary to become a child of God (1 Pet. 1:22-23), grow as a child of God (1 Pet. 2:2), and arrive safely at the eternal destiny God has for His children/heirs (Acts 20:32). Every time you read God's word and feed upon its spiritual milk and meat, blessed is he who realizes he is tasting and seeing Jehovah's goodness.
You can taste and see God's goodness every Lord's Day when you remember the Lamb of God's death. As your mind focuses upon that black Friday at Mount Calvary and your tastebuds are stimulated by partaking of the unleavened bread and fruit of the vine, you can taste and see God's love and goodness.
Because of God's grace, Jesus tasted death for every man (Heb. 2:9). His death is not a cleverly devised fable. It is predictive prophecy which became a fact of history (1 Cor. 15:3-4). Verifiable, tangible, infallible proof of God's great love was driven into Earth's geography and human history at Golgotha. It is the ultimate, pre-eminent showcase of God's love (Rom. 5:8). Your tastebuds are witnesses to the Son of God's incarnation and crucifixion. Therefore, every Sunday when you commune with your Lord during His supper, you are blessed when you taste and see Jehovah's goodness.
"Oh, taste and see that the Lord is good!"
