When his master saw that the LORD was with him and made him prosper in all he did, — Genesis 39:3

Joseph was a slave in Potiphar's house, yet the Lord made everything he did prosper. His circumstances said "slave," but God's blessing said "Son." It's the same promise Jesus gave: seek first the kingdom, and everything else is added. God can cause a man to prosper in a prison cell if He chooses. Your circumstances don't limit His ability to bless.
