But I have trusted in thy mercy; my heart shall rejoice in thy salvation. But I have trusted in thy mercy - Thou wilt not suffer me to fall; or if I have fallen, wilt thou not, for his sake who died for sinners, once more lift up the light of thy countenance upon me? Wilt thou not cover my sin?
My heart shall rejoice in thy salvation - There is no true joy but of the heart; and the heart cannot rejoice till all guilt is taken away from the conscience.
