I wish that ye take pains for salvation. Mistaken grace, and somewhat like conversion which is not conversion, is the saddest and most doleful thing in the world. Make sure of salvation, and lay the foundation sure, for many are beguiled. Put a low price upon the world’s clay; but a high price upon Christ. Temptations will come, but if they be not made welcome by you, ye have the best of it. Be jealous over yourself and your own heart, and keep touches with God. Let Him not have a faint and feeble soldier of you. Fear not to back Christ, for He will conquer and overcome. Let no man scaur at Christ, for I have no quarrels at His cross; He and His cross are two good guests, and worth the lodging. Men would fain have Christ good-cheap; but the market will not come down. Acquaint yourself with prayer. Make Christ your Captain and your armour. Make conscience of sinning when no eye seeth you. Grace be with you.
