Psalms 51:13

Psalms 51:13. Then will I teach transgressors thy ways;

He would turn preacher if God would but bless him. He would tell others what great things God had done for him.

Psalms 51:13. And sinners shall be converted unto thee.

He felt sure that, if he once told his tale of love, others would he melted, and would turn to God; and no doubt it was the case.
