The Bible tells us in Romans 2:11 that there is no partiality with God, God has no favorite children. In Mark 9:23 Jesus said that all things are possible to those who believe and 1 Corinthians 12:6, 11 shows us that it is God Who works through people as He wills. God may use different people in different ways but it is still God working through that person.
We can look at the disciples of Jesus for an example here. Jesus picked twelve men from various backgrounds to follow Him and carry out His work. Jesus did not just select a certain class of people or people who had some special abilities, Jesus picked ordinary men who became extraordinary when they followed Him and acted on what He said. The same is true for people we read about in the book of Acts, God uses all kinds of people to do His will.
Today God is looking for people that He can use and we need to be ready to work with God. If we think that God and His Word work differently for some people based purely on some preference God has or that person being special then we are limiting ourselves and God. Jesus said in Mark 11:23 that whoever speaks to the mountain and does not doubt in his heart will have whatever he is saying. Remember, God's Word works the same for everyone everywhere but we still have to put it to work. Find out what God has to say about you and your life then believe it and act on it; you'll be glad that you did!
