Peter wrote to discouraged and fearful believers that they were being guarded by God's power through faith for a salvation ready to be revealed in the last time (1 Peter 1:5). That is feet-planting, backbone-bracing, head-lifting assurance! Augustus Toplady wrote a poem about this:
A Sov’reign Protector I have,
Unseen, yet forever at hand,
Unchangeably faithful to save,
Almighty to rule and command.
He smiles, and my comforts abound;
His grace as the dew shall descend;
And walls of salvation surround
The soul He delights to defend.
Inspirer and Hearer of prayer,
Thou Shepherd and Guardian of Thine,
My all to Thy covenant care
I sleeping and waking resign.
If Thou art my Shield and my Sun,
The night is no darkness to me;
And fast as my moments roll on,
They bring me but nearer to Thee.
Kind Author, and ground of my hope,
Thee, Thee, for my God I avow;
My glad Ebenezer set up,
And own Thou hast helped me till now.
I muse on the years that are past,
Wherein my defense Thou hast proved;
Nor wilt Thou relinquish at last
A sinner so signally loved!
We will sing this hymn this Lord's Day, as well as consider from the Scriptures the great truth of God's preservation.
