Psalms 71:17

The psalmist declares that the righteousness of Christ, and the great salvation obtained thereby, shall be the chosen subject of his discourse. Not on a sabbath only, but on every day of the week, of the year, of his life. Not merely at stated returns of solemn devotion, but on every occasion, all the day long. Why will he always dwell on this? Because he knew not the numbers thereof. It is impossible to measure the value or the fulness of these blessings. The righteousness is unspeakable, the salvation everlasting. God will not cast off his grey-headed servants when no longer capable of labouring as they have done. The Lord often strengthens his people in their souls, when nature is sinking into decay. And it is a debt which the old disciples of Christ owe to succeeding generations, to leave behind them a solemn testimony to the advantage of religion, and the truth of God's promises; and especially to the everlasting righteousness of the Redeemer. Assured of deliverance and victory, let us spend our days, while waiting the approach of death, in praising the Holy One of Israel with all our powers. And while speaking of his righteousness, and singing his praises, we shall rise above fears and infirmities, and have earnests of the joys of heaven. The work of redemption ought, above all God's works, to be spoken of by us in our praises. The Lamb that was slain, and has redeemed us to God, is worthy of all blessing and praise.

O God, thou hast taught me from my youth. It was comfortable to the psalmist to remember that from his earliest days he had been the Lord's disciple. None are too young to be taught of God, and they make the most proficient scholars who begin betimes. And hitherto have I declared thy wondrous works. He had learned to tell what he knew, he was a pupil teacher; he continued still learning and declaring, and did not renounce his first master; this, also, was his comfort, but it is one which those who have been seduced from the school of the gospel, into the various colleges of philosophy and scepticism, will not be able to enjoy. A sacred conservatism is much needed in these days, when men are giving up old lights for new. We mean both to learn and to teach the wonders of redeeming love, till we can discover something nobler or more soul satisfying; for this reason we hope that our gray heads will be found in the same road as we have trodden, even from our beardless youth.
