[2 Chronicles 16:9a] For the eyes of the Lord roam to and fro over all the earth, to show Himself strong on behalf of those whose hearts are fully devoted to Him. God searches for individuals who are willing to go and do what he wants to get done. And many of those he chooses are not those who you'd think were qualified for the task.
One of my favorite examples of this is when God chose Esther the orphan girl to become queen. Married to the king put her in the ideal place to help save the Jewish people from destruction. When God chose her he also gave her courage to take risks, helped her find favor with others, and made available everything else she needed to succeed.
