How you become clean?

Cleaning

New King James Version (NKJV)

3 You are already clean because of the word which I have spoken to you.

Bathing = whoever believes in Him

Everlasting means = Lasts for ever, it can never be lost.

New King James Version (NKJV)

8 Peter said to Him, “You shall never wash my feet!”

Jesus answered him, “If I do not wash you, you have no part with Me.”

9 Simon Peter said to Him, “Lord, not my feet only, but also my hands and my head!”

10 Jesus said to him, “He who is bathed needs only to wash his feet, but is completely clean; and you are clean, but not all of you.”

but not all ==> Jesus saying about Judas, who is to betray Jesus

New King James Version (NKJV)

16 For God so loved the world that He gave His only begotten Son, that whoever believes in Him should not perish but have everlasting life.
