If we are going to be effective in God's Kingdom here on Earth, we must learn to humble ourselves by abandoning our opinions and seek after His will for our lives. God has personalised revelations that He desires to share with each of us on a daily basis. To tap into the things that He has for us, we must put aside everything that is at our disposal for learning and instead go directly to God and say: "What do you have for me today?"
Jesus gave then this answer: "I tell you the truth, the Son can do nothing by Himself; He can do only what He sees His Father doing, because whatever the Father does the Son also does.
Jesus did only the things that He saw His Father(God) doing. We read in various places in the New Testament about how Jesus spent much time in prayer...sometimes praying all night. He would withdraw to lonely places and pray early in the morning and any time during the day.
I believe that spending time in prayer is the key for directly hearing the voice of God. It's a good idea to have your Bible during these times of prayer. Often times we will be guided by the Holy Spirit to look at a particular passage which God will speak to us through.
