John 4:23
But the hour is coming and now is when the true worshippers will worship the Father in spirit and in truth, indeed. For the Father, He seeks worshippers as these. Because YHWH is Spirit and those who worship they must worship Him in spirit and truth.
John 15:26
But when the Redeemer comes, He Whom I will send to you from the presence of my Father, the Spirit of Truth, He Who proceeds from the presence of my Father will witness concerning me. You will also testify for you were with me from the start.
John 16:12
Again I have much to say to you but you are not able to grasp it now. But when the Spirit of Truth comes He will guide you in all truth, for He does not speak from His own mind but He will speak everything that He hears (directly from YHWH).
Yah set the pattern in the beginning teaching that faith in Him and living according to His Instructions were the means to walk His path of righteousness. Today it is that same faith we show in accepting the shed blood of His Son renewing Yah's covenant wherein we abide by The Father's Instructions in Spirit and in Truth. Much has changed on this earth since Abraham was called out from the pagan lifestyle in Ur of Chaldea, but Yah's Word never changes. It is by His Spirit given us through faith and our testimony of His Son that we learn to worship our Creator in Spirit and in Truth.
