God is not distant or removed from mankind. We often struggle with the fact that God is not tangible or visible as material matter that we can relate to. If God was material, mankind would attempt to define God, rationalize God or contain God. Since God is in a different dimension than we are, man either finds God to be greater than we are, or man has determined that God does not exist.
God has revealed Himself to man in a number of ways:
1) Creation. All that God has created reveals Himself and His handiwork to us. So often in Scripture when mankind struggles with understanding God, God points man to His creation (Book of Job and Isaiah).
2) Jesus Christ. God has revealed Himself to man through the person and work of Jesus Christ. God Almighty taking on the form of flesh in the person of Christ.
3) The Word of God. God has revealed Himself to mankind through the Holy Scriptures. All of the Word of God is verbally inspired and alive for you and me.
4) The Holy Spirit. The Holy Spirit, sent from God to dwell in the life of the Christian has revealed God to man. This revelation should be very evident to the believer to whom He is given, but also to the unbeliever in how He has impacted and changed the lives of the saved.
5) Israel. God revealed Himself in the past and He will reveal Himself once again through the Nation of Israel and His workings and dealings with them.
6) The Book of Revelation. God allowed the Apostle John to be transported as a spectator to the throne of God in a vision which John has given to us in the Book of Revelation. We can get a glimpse of God and Heaven through the eyes and pen of the Apostle John in Revelation chapters 4 and 5.
