So this is rubbish?
"Taste and see that the Lord is good! Blessed is the man who takes refuge in Him." Psalm 34:8
This verse is a joyful directive to born again believers to continually exercise their singular ability to partake of, and enjoy, God's infinite goodness.
1. You are assuming that the verb "taste" in this verse must mean a short, practical, subjective trial like wine tasting, pie judging or test driving a car. Tasting can be a sampling to test flavour as you suggest but the primary meaning is to "perceive or experience the flavour" of something and has no time limitation as is necessary with an experiment.
2. You are assuming that "taste" here is an open invitation to sample God's attributes and derive a clinical analysis of His goodness. The verse, however states emphatically 'that the Lord is good' and leaves no room for opinion. Seeing that the original is in the imperative mood, for both "taste" and "see", and there are no modifiers, it is a command and not a simple invitation. He is not open to analysis.
3. You are assuming that this directive to taste and see is open to anyone and not restricted to believers. This runs contrary to the harmony of the scriptures. Personal verification regarding God's goodness can only be made by those who have been regenerated by God's Spirit. Indeed, tasting, in this spiritual sense, can only be a savouring of God's goodness by those who, as the rest of the verse says, have taken "refuge in him" and as verse 3 says, those who are capable of exalting the name of the Lord together with David.
Yes; I suggest that only rubbish theology can come to the conclusion that the creature can, in any respect, sit in judgement on the Creator.
