O Taste and see that the LORD is good!
Blessed is the man who takes refuge in Him!
To taste something is to have a very direct experience of it. What relevance does taking refuge have to do with experiencing the LORD’s goodness? Well, as always, context helps — look at verses 6-7;
This poor man cried, and the Lord heard him
and saved him out of all his troubles.
The angel of the Lord encamps
around those who fear him, and delivers them.
David was in serious danger when he wrote this psalm, so his direct experience of God was of His lifesaving protection. Which raises the question to me of whether I actually take refuge in God or just think nice fuzzy thoughts about resting in Him it but do not really trust Him as my place of safety?
Consider those blessed of Matthew 5:11-12; if we make Jesus our refuge and put all our hope in him, we are more likely to be persecuted for such zeal. Yet in such persecution Christians testify experiencing a deep assurance of Christ’s presence, they taste for themselves his trustworthiness as a refuge.
Blessed are you when others revile you and persecute you and utter all kinds of evil against you falsely on my account. Rejoice and be glad, for your reward is great in heaven, for so they persecuted the prophets who were before you. (Matthew 5:11-12 ESV)
