We have all the faith we need, no larger than a mustard seed. But what is
its root, and how mature is it? We know for certain many things we cannot (yet)
see. Our faith is built on God's promises, the firmest foundation. God told
Abraham, a retiree, to go forth in faith - not telling him details - and He made
a way for him to Israel.
There is no security apart from God's promises, no matter how much
insecurity or apparent security we have in this world, our concentration camp.
Should this discourage us? No; when in doubt, remind yourself of His promises,
of your eternal home with Him. Tell stories from the Word of faithful men who
walked not by sight. God doesn't promise earthly security; rather, He guarantees
heavenly security. So walk always by faith. God is secure; He will bring you
Soli Deo gloria.
