Build on what God has given you
Jerusalem had a temple but there was no protection for the city from further attack. Nehemiah travels to Jerusalem and uses his leadership skill to rally a citywide construction crew. Within a few weeks, the walls around Jerusalem were built and standing tall and their enemies lost their confidence.
Nehemiah's leadership was built not so much on ancestry from the Jewish lineage as by faithfulness. He would build the walls on faith. He was obscure in comparison to other great Old Testament heroes, but faithfulness separated him from mediocrity. God has given each leader specific gifts. Some are not as visible; all are useful.
"They are your servants and your people, whom you redeemed by your great strength and your mighty hand." - Nehemiah 1:10
