Psalm 8:3-6
[3]When I view and consider Your heavens, the work of Your fingers, the moon and the stars, which You have ordained and established,
[4]What is man that You are mindful of him, and the son of [earthborn] man that You care for him?
[5]Yet You have made him but a little lower than God [or heavenly beings], and You have crowned him with glory and honor.
[6]You made him to have dominion over the works of Your hands; You have put all things under his feet: [I Cor. 15:27; Eph. 1:22, 23; Heb. 2:6-8.]
The Bible verse that we read is telling us that men are so important in life, and in one junction or the other we will need the men to survive. This Bible verse, is showing us that even as great as God is is mindful of men.
Some people are fond of fighting with anyone, the person you are fighting right now maybe your benefactor, the one that you have fought in the past or the one you are about to fight. I want you to think on this "what are main that you are mindful of him".
As great as our God is, and as big as his plan is on Earth, He cannot administer them on his own, He needs men to do these. So also you, whatever what God will do for you you, He will use men. So be mindful of how you relate with men in life, your enemy today can be the assigned benefactor in your life.
Men are definitely God's method. I always have this at heart when I am dealing with men.
Like you said you never can tell who will be your benefactor tomorrow.
