And they that know thy name,.... As proclaimed in the Gospel, a God gracious and merciful, and forgiving sin; and as in Christ, in whom his name is, and in whom he is the God of love, grace, and mercy, though out of him a consuming fire; or the name of Christ himself, the Word of the Lord, who is the refuge of saints and sinners; his name Jesus, a Saviour: such who know him to be the able, willing, complete, all sufficient, and everlasting Saviour; who know his power and faithfulness to keep what is committed to him; and who know him not merely notionally and speculatively, and in a professional way only, but affectionately, spiritually, and experimentally: such will put their trust in thee; as they have great reason to do; and the more they know of the grace and mercy of God in Christ, and of the ability and suitableness of Christ as a Saviour, the more strongly will they place their trust and confidence in him; for thou, Lord, hast not forsaken them that seek thee: who are first sought out by God in the effectual calling, and then under the influence and direction of his grace and Spirit seek him in Christ, where he is only to be found; and seek Christ and his righteousness above all things else, and with their whole hearts, and diligently; and seek to Christ alone for life and salvation, and continue seeking the Lord, by prayer and supplication, for whatever they stand in need of; these God does not forsake: he may sometimes hide his face from them, as he does from his own children, and did from his own Son, yet he never forsakes them totally and finally; nor will he forsake the work of his own hands, which he has wrought in them, but will perfect it; he will never leave them so as that they shall perish by sin, Satan, or any enemy; he will not forsake them in life, nor at death, but will be the strength of their hearts, and their portion for ever.
