This precarious lifestyle brings home how much we truly rely solely in Him who "provides food for the cattle and for the young ravens when they call" (Psalm 147:9). We know we are worth much more than they are (cf. Matt 6:26). We also know that while we can do all things through Him (cf. Phil 4:13), we can do nothing without Him (cf. Jn 15:5). Which is why, when we find ourselves again with roof, food, and clothing, I raise my heart to the Lord to thank Him for His provision for my family.
One prayer I often use to this end is the ancient prayer "Non nobis Domine." A beautiful rendition is found in the movie adaptation of William Shakespeare's Henry V:
Non nobis, non nobis, Domine
Sed nomini tuo da gloriam.
(Psalm 139:9 - Vulgate)
which the King James version renders:
Not to us, not to us, O Lord,
But to thy name give glory.
