John Owen
The Gospel will teach a man to feel sin and believe righteousness at the same time. Faith will carry heaven in one hand and hell in the other; showing the one deserved, the other one purchased.

And I will give them one heart, and a new spirit I will put within them. I will remove the heart of stone from their flesh and give them a heart of flesh, that they may walk in my statutes and keep my rules and obey them. And they shall be my people, and I will be their God.
Ezekiel 11:19-20
