The Lord promises to protect us and keep us according to His will. The all-powerful God is our defense, provider and refuge in this life. Indeed, in our own strength we can do nothing, but through His strength we can do all things.
Philippians 4:11-13 KJV
Not that I speak in respect of want: for I have learned, in whatsoever state I am, therewith to be content.  I know both how to be abased, and I know how to abound: every where and in all things I am instructed both to be full and to be hungry, both to abound and to suffer need.  I can do all things through Christ which strengtheneth me.
