How can I know God's will?
Another way you can know the will of God is through prayer, when you commune with God and learn what pleases Him. The Bible says, "Let the peace of God rule in your hearts" (Col. 3:15). This means that the peace of God is like a regulator, so that when you violate the will of God, His peace leaves you and you have inner turmoil, immediately discovering you are going against God’s will. Knowing God’s Word and knowing the peace that comes about through a continuous relationship with Him are the best ways of knowing God’s will (John 15:4).
It is also true, however, that God will show us His will through a number of other means. He will show us His will through godly counselors (Prov. 19:20; 20:18; 24:6). We can also discern God’s will in part through circumstances; through the inner voice of the Spirit of God speaking to us; or through visions or dreams (Is. 1:1; Acts 2:17). He can reveal His will to us in many ways.
The key is to be sure that we are submitted to Him and are willing to do whatever He shows us. If we purpose to do His will, we will know His leading.
Finally, for people who seemingly are unable to discern God’s positive directions, I recommend "negative" guidance. Say, "Father, I want Your will above all else. Please do not let me miss Your plan and purpose for my life." Such surrender has the guarantee of His guidance (Prov. 3:5, 6).
