OK - I believe the Bible teaches that he guaranteed your salvation in full, provided you trust in him and him alone:

Joh 10:15  just as the Father knows me and I know the Father; and I lay down my life for the sheep.

Joh 10:27-30  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.”

Philippians 1:6 And I am sure of this, that he who began a good work in you will bring it to completion at the day of Jesus Christ
