That sounds really good and all... But how does one really walk by the Spirit? It is some esoteric state of mind? Isn't the Word of God supposed to be used in conjunction with the Spirit of God in order to be a faithful Christian? Some practical examples would be appreciated, thanks much.
It is not at all esoteric. Before Jesus ascended He said that it was needful for Him to go so that He might send another comforter, the Holy Spirit of God. He told the disciples that up to that point He had been with them, but would be IN them. On the day of pentecost, 120 at least were filled with the Holy Spirit and 3000 were saved (many of whom I believe probably received the same Holy Spirit baptism at the same time.)
Being filled with the Holy Spirit and led by the Spirit is central to being a Christian. In 1 Cor. 2 we read that no one knows what is in the heart of a man save that man. Likewise no one knows what is in the heart of God save God himself. Christ knows what is in the heart of God, and through the Holy Spirit, we have the mind of Christ. God reveals His will and His heart to us as we walk in the Spirit.
He does this several ways. Sometimes He just puts within us a strong desire that we can learn to recognize as His will. Psalm 37:4. Often He speaks to us directly. This usually comes through what we percieve as a stream of thoughts that we recognize as His voice. We do use the word of God in all both of these cases as a check on what we as fallible people hear. We learn over time to be more and more sensitive to the voice of the Master, but we acknowledge our own weakness and ALWAYS run it through the filter of the written word. Remember that we have a more sure word of prophecy 2 Peter 1:19, and that God has exalted His word even above His NAME (Psalm 138:2).
Learning to walk by the Spirit is a process. At its foundation is intimate relationship and fellowship with the Lord. I don't know if you have received the baptism of the Holy Spirit as in Acts 2, Acts 10, Acts 19, etc. If not, begin to ask God to fill you with the fullness of His Spirit. Also, begin in your prayer times to ask God to help you to recognize His voice and to speak to you His will. Begin to draw near to Him just for the sake of knowing Him.
When I was 18 I was struggling with whether to accept a full ride scholarship to a local college or to give it up to attend a local Bible college. I had many well meaning CHristians pressuring me to attend Bible college. I prayed about the decision for some time. One night while praying about this, the Lord just gave me an assurance. No audible voice, not miraculous sign, just a calm assurance in my spirit of what I was to do. I took advantage of the scholarship, forgot about Bible college, and in hindsight can see the plan of God unfolding through that decision. It would have been a mistake for me to have given up the scholarship.
Another time at a church camp a girl collapsed into unconciousness after the evening service. I was talking with a couple friends on a hill overlooking the open walled tabernacle where we have services. People gathered around and began to pray for the girl. The Holy Spirit spoke a strong thought in my mind, "You have to get down there right now." I had no reason to think that. Many were praying for her, and at that point I did not know but what she simply did not feel well. I quickly obeyed and once there began to pray for the girl. She had absolutely no response to any pain stimulus like pricking her hands for feet, etc. As I prayed the Holy Spirit's presence seemed to come over me very strongly and I remember finally commanding strongly, "Come out, come out, come out!" Immediately she snapped back into conciousness and was perfectly fine the rest of the week. I later found out that there was a teen on the grounds that had been heavily involved in the occult and admitted to praying that this girl die that very day, although he could not explain why he had prayed that.
Another time I had ignored the voice of the Lord. I knew He was telling my wife and I to leave a church, but we had no logical reason to do so. Things were going well and we were very active in ministry. Finally as we drove to church one morning the Lord spoke strongly in my mind, "Are you going to do what I said or not?" I immediately repented of my rebellion and we obeyed. Had we not obeyed I would not be where I am today.
These are just a few of my own examples. Hope this helps.
