Taking the Wind out of the Muslim’s Sails

Yeshua (Isa) (pbuh) instituted true worship to his Father, YHWH (pbuh) on the Day of Pentecost 50 days after he rose from the dead. It is written in Jn 4:20-24:
Our (your) fathers worshipped in this mountain; and ye say, that in Jerusalem is the place where men ought to worship. 21 Jesus saith unto her, Woman, believe me, the hour cometh, when ye shall neither in this mountain, nor yet at Jerusalem, worship the Father. 22 Ye worship ye know not what: we know what we worship: for salvation is of the Jews. 23 But the hour cometh, and now is, when the true worshippers shall worship the Father in spirit and in truth: for the Father seeketh such to worship him. 24 God is Spirit: and they that worship him must worship him in spirit and in truth.KJV

Anytime you read BUT anywhere, it is a time for a pause, because everything written before that word is about to be altered by everything written after it. Jesus Christ instituted TRUE UNDENIABLE WORSHIP, which is truly spiritual. On Pentecost the disciples of Yeshua spoke in the tongues of men and angels for the first time in history. (You can read about it in Acts 2.)
No one can any longer bullshit anyone else about worshipping the One True God, YHWH. The apostle Paul speaks more about it in 1 Co 14:1-5
Follow after charity, and desire spiritual (pneumatikos), 2 For he that speaketh in a tongue speaketh not unto men, but unto God: for no man understandeth (what he is speaking) howbeit IN THE SPIRIT he speaketh secrets. 4 He that speaketh in a tongue edifieth himself; 5 I would that ye all spake with tongues, KJV

Speaking IN THE SPIRIT is speaking in a language that you yourself do not understand (secrets) and it is UNTO GOD. This is how a true worshipper, worships. We can praise the Lord Jesus Christ but true worshippers do so in spirit and in truth in the direction of God, the Almighty.

Allah is a false god and those who worship him are false, deceived worshipers. They are sincere in what they believe. As I have always said, Anyone can believe anything they want to, but whether it is true or not is another story. People used to believe that the world was flat

There is only one True God and he calls himself YHWH.
