Who is saying they can do what they want? No one I know, either here, in real life, in seminary or any place else. I don't know where people pick up these straw men!?
Sincerely I am a born again, new creature in Christ and the Bible has shown me over and over that we are saved forever not just until we make our first mistake. And certainly not from sin. And we are not born again over and over, losing our salvation when we sin, and then gettin it back when we are walking perfectly with God.
That is the whole point - we walk after the Spirit and the Spirit of God leads us.
Can you deny that the Spirit of God is leading me, and many others? I know whom my Redeemer is, and I am persuaded that he will keep me against that day!
"
For this reason I also suffer these things, but I am not ashamed; for I know whom I have believed and I am convinced that He is able to guard what I have entrusted to Him [a]until that day." 2 Tim. 1:12
Just one last word about slandering people who believe that God has saved them unconditionally, by calling them antinomians.
The word "slanderous" in Greek is "diabolos." That means "of or from the devil." So by slandering other followers of Christ you are being used of the enemy. I am sure you did not mean it that way, but it might be best to rethink your unjustified straw men attacks!
God bless!
