All of Grace.
God's people, after they are called by grace, are preserved in Christ Jesus; they are "kept by the power of God through faith unto salvation;" they are not suffered to sin away their eternal inheritance, but as temptations arise, they have strength given with which to encounter them; and as sin defiles them, they are washed afresh, and again cleansed. But mark, the reason why God keeps His people, is the same as that which made them His people—His own free, sovereign grace. If you have been delivered in the hour of temptation, pause and remember that you were not delivered for your own sake. There was nothing in you which deserved the deliverance. If you have been fed and supplied in your hour of need, it is not because you have been a faithful servant of God, or because you have been a prayerful Christian; it is simply and only because of God's mercy. He is not moved to anything He does for you by anything which you do for Him; His motive for blessing you lies wholly and entirely in the depths of His own bosom. Blessed be God, His people shall be kept.
"Nor death nor hell shall e'er remove
His favorites from His breast;
In the dear bosom of His love
They must forever rest."
But why? Because they are holy? Because they are sanctified? Because they serve God with good works? No, but because He, in His sovereign grace, has loved them, does love them, and will love them to the end. Thus, salvation from first to last is all of grace. Then how humble a Christian ought to be! We have nothing whatever to do with our salvation; God has done it all. It is mercy undeserved which we have received. It is His boundless, fathomless love which has led Him to save us; and it is the same love and mercy which upholds us now. To Him be glory!
