My enemies and my weapons

I am happy that my enemies have good enough weapons. My weapons are made by my enemies because i have no time to make them but only to use them. If Goliath doesn't come with his sword, how can I kill him? i did not make a big one. If red sea did not block my way, where would i drown Egyptians? It is good that Haman made a tallest gallows for me because I cannot make it to hang him. I am happy that Canaanites are giants and strong since the soil there was difficult to cultivate but they prepared it for me before i go there. Oh God, how much you love me!

Oh, the depth of the riches and wisdom and knowledge of God! How unsearchable are his judgments and how fathomless his ways! ​​​​​​​For who has known the mind of the Lord, ​​​​​​or who has been his counselor? ​​​​​​​Or who has first given to God, ​​​​​​that God needs to repay him? For from him and through him and to him are all things. To him be glory forever! Amen.

(Rom 11:33-36 [NET])
