He saved me, and now I choose to live for Him. No, that does not differ from what we believe and teach. As stated, the decision to live for Christ follows salvation, and salvation assumes conversion. However, we do not believe that God predestined anyone to eternal punishment because the Bible does not teach an election to damnation. If it is so, where in the Bible does it say that we are in debt with God.
Salvation is a free gift.
There are, nevertheless, numerous Bible passages which speak of our service to God as a duty or obligation. It is our duty to show our gratitude for his grace by willing obedience. We are motivated not by a sense of obligation but by love. It is always safest to strive to use the language of Scripture when presenting or describing Bible doctrines. People are doomed always and only because of their despising of the gospel, not because they are not elected.
