I think you are abusing His word to keep up your works based, glory usurping, God reducing "you can lose salvation" false doctrine. You're adding to scripture to make it say that. So in John 10 is He ONLY talking about the disciples?
John 10
22 At that time the Feast of Dedication took place at Jerusalem. It was winter, 23 and Jesus was walking in the temple, in the colonnade of Solomon. 24 So the Jews gathered around him and said to him, “How long will you keep us in suspense? If you are the Christ, tell us plainly.” 25 Jesus answered them, “I told you, and you do not believe. The works that I do in my Father's name bear witness about me, 26 but you do not believe because you are not among my sheep. 27 My sheep hear my voice, and I know them, and they follow me. 28 I give them eternal life, and they will never perish, and no one will snatch them out of my hand. 29 My Father, who has given them to me, is greater than all, and no one is able to snatch them out of the Father's hand. 30 I and the Father are one.”
So is He only talking about certain sheep of His here? How do you warp this one to fit the powerless silly God that saves people that will throw it back in His weak face? I guess those that lose there salvation just weren't as good as you huh? They just don't measure up to your strength and glory. I sure hope you thank yourself for being so strong despite a God that can't keep you. Glory to you right?
