1 John 2:27
But you have received the Holy Spirit, and he lives within you, so you don’t need anyone to teach you what is true. For the Spirit teaches you everything you need to know, and what he teaches is true—it is not a lie. So just as he has taught you, remain in fellowship with Christ.
The Holy Spirit is the One who helps us to get revelation of the things of God in our heart. When revelation comes faith is there. It’s like walking into a dark room not being able to see the way out and then the Holy Spirit flips the light switch on. Once that happens you can see the way to go and act upon the Word of God. This is why we need to develop and maintain a close relationship with the Holy Spirit. Without such revelation we only have head knowledge, not heart revelation of the Word that produces faith. To develop this relationship one should receive the promise of the Father Jesus spoke about in the first chapter of the book of Acts. You will find out this promise was not to be born again, for Jesus had already breathed on His disciples and they had received the Holy Spirit. The promise of the Father was to be baptized in the Holy Spirit in which He would come upon them. Once you have received this promise you should pray in the Holy Spirit every day. The apostle Paul who walked in great revelation of the Word said to the Corinthians that he prayed in tongues more than all of them. This is how we can maintain our relationship with this great Teacher we have been given. Also do not do things to quench, resist, or grieve the Spirit. Doing so will weaken your relationship with Him. If you are in a church that denies the ministry of the Holy Spirit you should find another church. They are denying the help of the Spirit of God in their church. So develop and maintain you relationship with the Teacher, the Holy Spirit, and He will help you to receive revelation of the things of God.
