Asking God
I believe there are decisions where Christians need to hear directly from God before proceeding. For the most part, however, God has told us what He wants and how He wants us to behave in His Word. He expects us to love Him and love people. He expects that we tell others about Him. He expects us to care for those who are in need. He expects us to serve. He expects us to pursue holiness, to chase after Him and become more like Him every day. He expects us to avoid sin, to confess when we mess up and ask for forgiveness. He expects we make restitution before Himself and others. He expects us to live in this world, in the mess of this world, without being a part of this world.
