This is not a promise if we consider only the words but it is truly so as to its sense...
For David spoke a word which the LORD endorsed by making it true.
He argued from past deliverance's that he should receive help in a new danger.
In Jesus all the promises are "Yea" and "Amen" to the glory of God by us...
And so the LORD's former dealings with His believing people will be repeated.
Come, then, let us recall the LORD's former lovingkindness.
We could not have hoped to be delivered aforetime by our own strength yet the LORD delivered us.
Will He not again save us?
We are sure He will.
As David ran to meet his foe, so will we.
The LORD has been with us, He is with us, and He has said, "I will never leave thee, nor forsake thee,"...
Why do we tremble?
Was the past a dream?
Think of the dead bear and lion.
Who is this Philistine?
True, he is not quite the same, and is neither bear nor lion...
But then God is the same, and His honor is as much concerned in the one case as in the other.
He did not save us from the beasts of the forest to let a giant kill us.
Let us be of good courage.
