But the hour is coming, and is now here, when true worshippers will worship the Father in spirit and truth, for the Father seeks such as these to worship Him. God is spirit and those who worship Him must worship in spirit and truth. John 4:23, 24.
We call God Our Father because He is the source of our being. Like any good father, God protects us and provides for us. He advises us and teaches us. God is the model father. But we can't hug Him.
God is pure spirit. His image and His likeness are both spiritual. Let's be glad about that. It would be impossible to reshape our faces, or make ourselves taller If it was a body image we had to emulate. To worship only with the body; to take it to church, or make it fast or say prayers without the spirit is not good enough. God wants to be worshipped in the spirit because He is Spirit.
To understand spirit, let's think of attitude, emotion, desire, intelligence and personality. Spirit is everything a person is, but without the body. The Holiest Spirit brims with love, joy, peace, patience, kindness, goodness, long-suffering, mildness, fidelity, modesty, continence and chastity.
Truth is reality, pure and clear, unblemished, not distorted. Truth is as honest as a thermometer, as real as the sunrise, as pure as a drop of H2O. One can try to hide it, or warp it, or flat out deny it, but Truth will always bounce back to its original shape no matter how much abuse it gets.
Jesus told Pilate that He came into the world to testify to the truth and that everyone who belongs to the truth listens to His voice. To follow Christ, to listen to Him, to obey His commands, these Marks, is to belong to the truth. Let's listen to Jesus Christ tell us how to worship the Father.
