Charles Spurgeon Commentary 2 Peter 1:12

"Wherefore I shall be ready always to put you in remembrance of these things, though ye know them, and are established in the truth which is with [you]." — 2 Peter 1:12 (ASV)

Therefore I will not be negligent to put you always in remembrance of these things.

He who exhorts others to be diligent must not himself be negligent, and Peter most appropriately writes, Wherefore I will not be negligent to put you always in remembrance of these things.

Wherefore I will not be negligent to put you always in remembrance of the things, though ye know them, and be established in the present truth.

We are not merely to preach new truths which people do not know, but we are also to preach the old truths with which they are familiar. The doctrines in which they are well established are still to be proclaimed to them. Every wise preacher brings forth from the treasury of truth things both new and old—new, that the hearers may learn more than they knew before; old, that they may know and practice better that which they do already know in part.
