Gospel repentance is TURNING FROM YOUR OWN WORKS in order to satisfy God's demands for eternal life and simply TRUSTING - RESTING in the finished works of Jesus Christ as your ONLY hope for eternal life.
That requires acknowledgement that you are a sinner, condemned under the Law of God (Rom. 3:19-23) and all your works "come short of the glory of God" and thus feel your need of a Savior and receive the good news of the Gospel, and rest upon the good news of the gospel as YOUR ONLY HOPE of salvation. This is obedience to the Gospel! Refusing to acknowledge you are sinful and all your works come short of the glory of God is disobedience to the gospel. Attempting to contribute, assist, participate by YOUR WORKS in obtaining eteral life is repudiation of the FINISHED work of Christ and repudiation of the SUFFICIENCY of his satisfaction of ALL GOD's RIGHTEOUS demands against you.
Once, SAVED, then living for Christ is living in DEPENDENCE upon the power of the indwelling Spirit of God to serve God through obedience to his commandments NOT TBTAIN eternal life but to GLORIFY GOD by your life and experience the blessing of salvation here and now and eternal rewards to come. We serve out of LOVE not out of fear that we will lose what we never could obtain by our works.
The true people of God are those who OBEY the gospel in this manner and SERVE God in this manner and all other are unbelievers and self-righteous religious hypocrits.
Here is the summation of the issue of obedience to God.
BTAIN eternal life but to GLORIFY GOD by your life and experience the blessing of salvation here and now and eternal rewards to come. We serve out of LOVE not out of fear that we will lose what we never could obtain by our works.
