First. The heart, before it is broken, is hard and stubborn, and obstinate against God, and the salvation of the soul (Zech 7:12; Deut 2:30, 9:27).
Second. It is a heart full of evil imaginations and darkness (Gen 18:12; Rom 1:21).
Third. It is a heart deceitful and subject to be deceived, especially about the things of an eternal concernment (Isa 44:20; Deut 11:16).
Fourth. It is a heart that rather gathereth iniquity and vanity to itself than anything that is good for the soul (Psa 41:6, 94:11).
Fifth. It is an unbelieving heart, and one that will turn away from
God to sin (Heb 3:12; Deut 17:17).
Sixth. It is a heart not prepared for God, being uncircumcised, nor for the reception of his holy word (2 Chron 12:14; Psa 78:8; Acts 7:51).
Seventh. It is a heart not single, but double; it will pretend to serve God, but will withal lean to the devil and sin (Psa 12:2; Eze 33:31).
Eighth. It is a heart proud and stout: it loves not to be controlled, though the controller be God himself (Psa 101:5; Prov 16:5; Mal 3:13).
Ninth. It is a heart that will give place to Satan, but will resist the Holy Ghost (Acts 5:3, 7:51).
Tenth. In a word, 'It is deceitful above all things, and desperately wicked'; so wicked that none can know it (Jer 17:9).
