Charles H. Spurgeon on Psalms 105:4

Seek the Lord, and be strengthened; so divers ancient versions read it. They that would be "strengthened in the inward man, " must fetch in strength from God by faith and prayer. "Seek his strength, "and then seek his face; for by his strength we hope to prevail with him for his favour, as Jacob did, Ho 7:3. "Seek his face evermore, "i.e., seek to have his favour to eternity, and therefore continue seeking it to the end of the time of your probation. Seek it while you live in this world, and you shall have it while you live in the other world, and even there shall be for ever seeking it, in an infinite progression, and yet be for ever satisfied in it. Matthew Henry.
