Honey Out Of The Rock - Advice To My Own Heart And Yours

You are a religious person and partake of all the ordinances. You do well: they are glorious privileges: but if you have not the blood of Christ at the root of your religion, it will wither, and prove but painted pageantry to go to hell in.
If you retain guilt and self-righteousness under it, those vipers will eat out all the vitals of it at length. Try and examine with greatest strictness every day, what ground your religion and hope of glory is built upon, whether it was laid by the hand of Christ. If not, it will never be able to endure the storm that must come against it; Satan will throw it all down, and great will be the fall thereof (Matt 7:27).
You that glory in being a Christian, you shall be winnowed. Every vein of your profession will be tried to purpose. It is terrible to have it all come tumbling down, and to find nothing but itself to stand upon.
You who pride yourself on being a Christian, see to your waxen wings, which now will melt with the heat of temptation.
What a misery is it to trade much, and be bankrupt at length, and have no stock, no foundation laid for eternity in your soul!
