How do I know God's will for my life?
Most of God's will is already published and not in question: be holy, give thanks, avoid immorality, love your neighbour. Do that, and the undecided part gets much smaller. For the rest, use the ordinary means — Scripture, wise counsel from people who will tell you no, honest assessment of your gifts, the door that is actually open, and prayer. God guides moving people more often than parked ones; make the most faithful decision you can see and trust Him to steer.

For this is the will of God, even your sanctification, that ye should abstain from fornication:

Where no counsel is, the people fall: but in the multitude of counsellors there is safety.
Proverbs 11:14
The steps of a good man are ordered by the LORD: and he delighteth in his way.
