The sincere convert. Discovering the small number of true beleevers, and the great difficulty of saving conversion. Wherein is excellently and plainly opened these choice and divine principles: viz. 1. That there is a God, and this God is most glorious. 2. That God made man in a blessed estate. 3. Mans misery by his fall. 4. Christ the only Redeemer by price. 5. That few are saved, and that with difficulty. 6. That mans perdition is of himself. Whereto is now added the Saints jewel, shewing how to apply the promise; and the Souls invitation unto Jesus Christ. By Tho. Shepard, sometimes of Emanuel Colledge in Cambridge.
