When Jesus appeared to Saul on the road to Damascus, Saul asked Him the two greatest questions anybody could ever ask: "Lord, Who are You?" and "What do You want me to do?"
In Acts 9:6, the Lord said to Saul, "… Arise, and go into the city, and it shall be told thee what thou must do." Jesus could not have given him a better promise: to tell him what to do.
And God will guide you too. He has a plan for your life. Psalm 37:23 says, "The steps of a good man are ordered by the LORD: and He delighteth in his way." In Psalm 32:8. God says, "I will instruct thee and teach thee in the way which thou shalt go: I will guide thee with Mine eye." Aren't those wonderful promises? Guidance is promised in the Word of God. We have a Father above us, controlling all things. We have the Savior beside us, directing our steps. And we have the Spirit within us, impressing our hearts. We can know His will.
