Unconditional acts of love are from God
I can't help it if you disagree with St. Paul.
Your idea is paulism that calls good evil and what Christ says
"No one has greater love than this, to lay down one's life for one's friends."- John 15:13
This is what the non Christian soldier did by giving his life for his friend
John 15: 1 1 2 "I am the true vine, and my Father is the vine grower. 2 He takes away every branch in me that does not bear fruit, and everyone that does he prunes 3 so that it bears more fruit. 3 You are already pruned because of the word that I spoke to you. 4 Remain in me, as I remain in you. Just as a branch cannot bear fruit on its own unless it remains on the vine, so neither can you unless you remain in me. 5 I am the vine, you are the branches. Whoever remains in me and I in him will bear much fruit, because without me you can do nothing.
6 4 Anyone who does not remain in me will be thrown out like a branch and wither; people will gather them and throw them into a fire and they will be burned. 7 If you remain in me and my words remain in you, ask for whatever you want and it will be done for you. 8 By this is my Father glorified, that you bear much fruit and become my disciples. 9 As the Father loves me, so I also love you. Remain in my love. 10 If you keep my commandments, you will remain in my love, just as I have kept my Father's commandments and remain in his love. 11 "I have told you this so that my joy may be in you and your joy may be complete. 12 This is my commandment: love one another as I love you.
13 5 No one has greater love than this, to lay down one's life for one's friends. 14 You are my friends if you do what I command you. 15 I no longer call you slaves, because a slave does not know what his master is doing. I have called you friends, 6 because I have told you everything I have heard from my Father. 16 It was not you who chose me, but I who chose you and appointed you to go and bear fruit that will remain, so that whatever you ask the Father in my name he may give you. 17 This I command you: love one another.
Some may believe in slavery; Jesus tells us that we are no longer slaves. But those who do not bear fruit ie works are pruned. Jesus chose us all and appointed us to bear the fruit that He wills. Those who do not, He will reject based upon the fruits which are non existent or not to His liking. We can do nothing without Him; but if we do nothing, we will be without Him.
Jesus tells us that we will remain in His love ie eternal salvation if and only if we love Him and each other.
