"But God hath chosen the foolish things of the world to confound the wise; and God hath chosen the weak things of the world to confound the things which are mighty." 1 Corinthians 1:27
When God chooses a person to do His work, He knows who to choose. He chose David to be king, but not because he looked like a king. He chose Esther to save her people, but not because she was a woman of great influence. He chose Gideon to be a judge in Israel and bring His people out from under the oppression to the Midianites, not because Gideon was a great warrior.
When God chooses a person He doesn't do it based on the same standards that we use. None of these people were "suited" for the job according to our standards, but they were according to God's. God doesn't always choose according to ability, skill, education, popularity, etc. Actually, just the opposite is usually true. His choice is usually the one who is the most unlikely. He chooses the weak and foolish. He chooses unlearned fishermen. He chooses the good and the evil.
The bottom line is this- God has a plan and He chooses the person that He deems as the one to fulfill that plan. He knows what He is doing- He doesn't make a mistake. If God has chosen you, He hasn't made a mistake. He knew what He was doing- He has a plan for you to fulfill. But, on the other hand, don't ever think that He "had" to choose you. Don't think that just because He chose you that you have "arrived". God can just as easily remove you from that place as He set you in that place. Never think more highly of yourself than you ought, remember, God used a donkey to talk to a wayward prophet.
Have a great day. God picks and chooses who He wants to fulfill the plan that He has.
