Just as the vow of ver. 1 passed into invocation, so does the personal experience of vv. 4-7 glide into exhortation. If such be the experience of poor men, trusting in Jehovah, how should the sharers in it be able to withhold themselves from calling on others to take their part in the joy? The depth of a man's religion may be roughly, but on the whole fairly, tested by his irrepressible impulse to bring other men to the fountain from which he has drunk. Very significantly does the psalm call on men to "taste and see," for in religion experience must precede knowledge. The way to "taste" is to "trust" or to "take refuge in" Jehovah. "Crede et manducasti," says Augustine. The psalm said it before him. Just as the act of appealing to Jehovah was described in a threefold way in vv. 4-6, so a threefold designation of devout men occurs in vv. 8-10. They "trust," are "saints," they "seek." Faith, consecration and aspiration are their marks. These are the essentials of the religious life, whatever be the degree of revelation. These were its essentials in the psalmist's time, and they are so to-day. As abiding as they, are the blessings consequent. These may all be summed up in one--the satisfaction of every need and desire. There are two ways of seeking for satisfaction: that of effort, violence and reliance on one's own teeth and claws to get one's meat; the other that of patient, submissive trust. Were there lions prowling round the camp at Adullam, and did the psalmist take their growls as typical of all vain attempts to satisfy the soul? Struggle and force and self-reliant efforts leave men gaunt and hungry. He who takes the path of trust and has his supreme desires set on God, and who looks to Him to give what he himself cannot wring out of life, will get first his deepest desires answered in possessing God, and will then find that the One great Good is an encyclopædia of separate goods. They that "seek Jehovah" shall assuredly find Him, and in Him everything. He is multiform, and His goodness takes many shapes, according to the curves of the vessels which it fills. "Seek ye first the kingdom of God ... and all these things shall be added unto you."
