Be diligent!

From Spurgeon's sermon, "Particular Election"

"...make your CALLING and ELECTION sure." 2 Peter 1:10

Be diligent in your faith. Take care that your faith is of
the right kind - that it is not a creed but a credence -
that it is not a mere belief of doctrine, but a
reception of doctrine into your heart, and the practical
light of the doctrine in your soul.

No man has any right to believe himself elect of God,
unless he has been renewed by God; no man has any right to
believe himself called, unless his life be in the main consistent
with his calling, and he walk worthy of that whereunto he
is called. Out upon an election that lets you live in sin!
Away with it! away with it!

The true Christian desires that day by day he may grow more holy;
that hour by hour he may be more thoroughly renewed, until
conformed to the image of Christ, he may enter into bliss eternal.
