God is a spirit singular denoted here, duet.6 4 Here o Israel, the Lord our God is one Lord. One here is echad in Heb. denotes one in number, not a compound unity that the Strong 's concordance emphatically suggest.

God is a Spirit. This is the Father by Himself. You cannot see Him but He can manifest Himself into what ever He wants. He did manifest Himself in the form of a Human in Jesus Christ our Lord. Yet He is small enough We can receive Him as a gift in baptism. His Spirit replaces the tables of Stone the 10 Commandments which is Gods total Righteousness and His Eternal Law is written in our hearts and minds. Upon obedience to the gospel of Jesus and Repentance, we receive three of the greatest gifts known to all of Mankind. 1 the remission of sin 2 the gift of the Holy Spirit and 3 we are added to His congregation of believers. Heb.10

I totally agree with the commentaries on Jhn 4:24. The thing here is that, it is the Lord Himself The Son, who knows The Father, has seen The Father, is sent of The Father and is one with The Father who is commanding or giving us instructions as to the acceptable way in which God is to be worshiped. All that is required of us is total obedience to His revealed will in order for us to be 'true worshipers '.If we are true worshipers then that places us in His presence.And if in His presence then our goal is not a too distant reality. We then should ask guide God for the fortifying providence of His Holy Spirit so that He finds us daily to be worthy of worshiping Him in His presence.

God is a spirit...... God a spirit. A spirit is a form that is in the true image and likeness of God. This is what was created in the 1st account of creation in Genesis chapter 1.

Jeus said unto Nicodemus,in (John3:6-7) That which is born of the flesh is flesh;and that which is born of the spirit is spirit.
Marvel not that I said unto thee,Ye must be born again.John 4:24 Jesus declares to the Samaitan woman. God is a spirit; They that worship Him must worship Him in spirit and in truth.
Must place an obligation or mandate,not optional, there is no benefit if it is not done in the spiritand in truth. Genesis (3:3-5)shows us how we should worship God with respect, humility,sincerety, honor and reverence Him. God did not have respect for Cain and his offering.It was not offered as worship. But unto Abel, God had respect unto Abel and his offering.Therefore, worship is very spiritual and makes connection with God. The nature of worship involves submission, with the whole soul, mind,feelings,emotions and desires. Worship involves a launching out into the deep so when you let that net down for that draw it is so great, you have no desire to come to where it is shallow.The Psalmist declares,deep rcalleth unto deep at thy water spout. Worship in spirit and in truth reveals the mind of God to His people.
