James 4:6-7 tells us: But He gives more grace. Therefore He says: God resists the proud, But gives grace to the humble. Therefore submit to God. Resist the devil and he will flee from you.
Submitting to God includes obeying the Bible. But it also includes yielding your will to God's call for your life. I have often run across Christians who insist that God has called them to teach, but who refuse to teach children's classes. It might be possible, but I have never seen one of them teach a good adult class.
We decide that we want to serve God, but then Satan motivates us to seek prestigious positions. So many Christians feel "called" to be leaders that churches have to hold elections, while the same churches beg for people to provide transportation, work in the nursery, give money to poor families, etc.
If you'll submit to God and accept whatever He tells you to do, He'll tell you what to do with your life.
