God Rewards Our Righteousnesses

"The LORD rewarded me according to my righteousness: according to the cleanness of my hands hath he recompensed me. For I have kept the ways of the LORD, and have not wickedly departed from my God. For all his judgments [were] before me: and [as for] his statutes, I did not depart from them. I was also upright before him, and have kept myself from mine iniquity. Therefore the LORD hath recompensed me according to my righteousness; according to my cleanness in his eye sight" (2 Sam. 22.21-25).

If God is irresistibly making David do these things then why is David speaking in terms of "my righteousness," "I have kept the ways of the LORD," "I did not depart," "I have kept myself from mine iniquity," and "the LORD hath recompensed me according to my righteousness"? How can God reward someone for their righteousness if such righteousness is irresistibly given to a person, thus, given no free choice in the matter? It would no longer be a reward then.

It is God's will that we turn to Him to serve Him but it is up to us to do God's will and follow Him.
