Let such as love Thy salvation say continually, “Let God be magnified.”-Psalm 70:4.

Before we can love God’s salvation, we must be seekers of it; hence we read, “Let all those that seek Thee rejoice and be glad in Thee.” There is a duty peculiar to seekers, let them see to it; and then there follows a further obligation peculiar to those who have found what they sought for. Let joy and rejoicing be first realised by the seeker through his receiving personally the grace of God and then let us go on to a stage further. The fresh convert has his business mainly within; it will be well for him if his heart can, in sincerity, be glad in the Lord. When believers are young and feeble they are not fit for the battle; therefore, let them tarry at home awhile, and under their vine and fig-tree eat the sweet fruits of the gospel, none making them afraid. We do not send our children to hard service; we wait till their limbs are developed and then appoint them their share in life’s labors. Let the newly called be carried like lambs in the Savior’s bosom and borne as on eagles’ wings. “Let all those that seek Thee rejoice and be glad in Thee.” But when men have advanced beyond the earliest stage, when they are persuaded that Christ is theirs, and that they have been adopted into the family of God, then let them cheerfully accept active service…Strong men have strength given them that they may bear burdens and perform labors; light is this burden and blessed is this labor. Let them say continually, “Let God be magnified.” ~ C.H. Spurgeon
