The story from Genesis 30:25-43 is a story about this very thing.  The Lord is the provider.  But the Lord gave Jacob wisdom, expertise, and resourcefulness to breed his flocks.  We find this throughout the Bible.  David’s building projects, Solomon’s Temple build, weapons of warfare that God’s people invented, and governmental laws were all given by God and done by the people of God.  One of the hallmarks of Christianity is the freedom of thought, invention, and resourcefulness that it brings.
