Oh boy, another one... :)
Yeah, you don't need to be saved more than once. :) Just once, and then kept by the power of God. Once the Father gives you to Jesus, He loses not one. This is what the Bible ~ Jesus ~ teaches:
"All that the Father gives Me will come to Me, and whoever comes to Me I will never cast out. For I have come down from heaven, not to do My own will but the will of Him Who sent Me. And this is the will of Him Who sent Me, that I should lose nothing of all that He has given Me, but raise it up on the last day. For this is the will of My Father, that everyone who looks on the Son and believes in Him should have eternal life, and I will raise him up on the last day.”
[John 6:37-40]
"Blessed be the God and Father of our Lord Jesus Christ! According to His great mercy, He has caused us to be born again to a living hope through the resurrection of Jesus Christ from the dead, to an inheritance that is imperishable, undefiled, and unfading, kept in heaven for you, who by God’s power are being guarded through faith for a salvation ready to be revealed in the last time."
[1 Peter 1:3-5]
Grace and peace to you.
