Your source raised many more questions than it answered. It misinterprets things and ignores all the Scripture that says that we are required to follow God, seek God, become holy, and be judged on our works. How can you possibly ignore so much Scripture?
Matt. 16:24, “Then Jesus told his disciples, “If anyone would come after me, let him deny himself and take up his cross and follow me.”
"God “will repay each person according to what they have done.” To those who by persistence in doing good seek glory, honor and immortality, he will give eternal life."
"Follow God’s example, therefore, as dearly loved children and walk in the way of love, just as Christ loved us and gave himself up for us as a fragrant offering and sacrifice to God."
"But among you there must not be even a hint of sexual immorality, or of any kind of impurity, or of greed, because these are improper for God’s holy people. 4 Nor should there be obscenity, foolish talk or coarse joking, which are out of place, but rather thanksgiving. 5 For of this you can be sure: No immoral, impure or greedy person—such a person is an idolater—has any inheritance in the kingdom of Christ and of God.[a] 6 Let no one deceive you with empty words, for because of such things God’s wrath comes on those who are disobedient."
"Live as children of light 9 (for the fruit of the light consists in all goodness, righteousness and truth) 10 and find out what pleases the Lord. 11 Have nothing to do with the fruitless deeds of darkness, but rather expose them"
"Be very careful, then, how you live—not as unwise but as wise, 16 making the most of every opportunity, because the days are evil. 17 Therefore do not be foolish, but understand what the Lord’s will is. 18 Do not get drunk on wine, which leads to debauchery. Instead, be filled with the Spirit, 19 speaking to one another with psalms, hymns, and songs from the Spirit. Sing and make music from your heart to the Lord, 20 always giving thanks to God the Father for everything, in the name of our Lord Jesus Christ."
And on and on and on and on....
And why do you think anyone would attempt any of these things, unless they had saving faith? Why do you guys continually throw up that straw man?
