The following two verses may be the most densely promise-packed verses in all the Bible. Each promise brings out a little different shade of the same truth.
My sheep hear My voice, and I know them, and they follow Me; and I give eternal life to them, and they will never perish; and no one will snatch them out of My hand. 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.
This blessed redundancy gave encouragement to author of "How Firm a Foundation" to do the same.
“The soul that on Jesus doth lean for repose,
I will not, I will not, desert to his foes;
That soul, though all hell should endeavor to shake,
I’ll never, no never, no never forsake.
