The surrendered life Does bring peace / blessing from God. And, of Course, it would be genuine. And it Is sort of a covenant between a person and God. It's being done in our heart. Romans 10:9 - 10 "that if you confess with your mouth the Lord Jesus and believe in your heart that God has raised Him from the dead, you will be saved. For with the heart one believes unto righteousness , and with the mouth confession is made unto salvation. vs 13 for who soever calls on the the
name of the Lord shall be saved." And the rest of that passage is worth spending a minute reading. vs 14 vs 17 says Faith comes by hearing, and hearing by the word of God.
that's a very negative concept of surrender. That's only done if a group is ambushed // no way out. And often time in that situation the group is killed in the process. And often time, the soldiers were issued cyanide capsules to be taken in case of emminent capture by the enemy. Because the enemy has a horrible way of turturing their captives.
God scourges those He loves!
