"Yet a time is coming and has now come when the true worshipers will worship the Father in spirit and truth, for they are the kind of worshipers the Father seeks. God is spirit, and His worshipers must worship in spirit and in truth." John 4:23-24
How do we worship Him in Spirit and in truth?
Through Christ Jesus living in us who is the truth and gives freely of His Spirit.
Jesus said to him, “I am the way, the truth, and the life. No one comes to the Father except through Me. John 14:6
"Therefore I urge you, brethren, by the mercies of God, to present your bodies a living and holy sacrifice, acceptable to God, which is your spiritual act of worship." Romans 12:1
"from the same mouth come both blessing and cursing. My brethren, these things ought not to be this way." James 3:10
"For those who are according to the flesh set their minds on the things of the flesh, but those who are according to the Spirit, the things of the Spirit. For the mind set on the flesh is death, but the mind set on the Spirit is life and peace, because the mind set on the flesh is hostile toward God; for it does not subject itself to the law of God, for it is not even able to do so, and those who are in the flesh cannot please God. However, you are not in the flesh but in the Spirit, if indeed the Spirit of God dwells in you But if anyone does not have the Spirit of Christ, he does not belong to Him. If Christ is in you, though the body is dead because of sin, yet the spirit is alive because of righteousness. But if the Spirit of Him who raised Jesus from the dead dwells in you, He who raised Christ Jesus from the dead will also give life to your mortal bodies through His Spirit who dwells in you.So then, brethren, we are under obligation, not to the flesh, to live according to the flesh--for if you are living according to the flesh, you must die; but if by the Spirit you are putting to death the deeds of the body, you will live." Romans 8:5-13
"In the same way the Spirit also helps our weakness; for we do not know how to pray as we should, but the Spirit Himself intercedes for us with groanings too deep for words; and He who searches the hearts knows what the mind of the Spirit is, because He intercedes for the saints according to the will of God. And we know that God causes all things to work together for good to those who love God, to those who are called according to His purpose." Romans 8:26-29
We urge you, brethren, admonish the unruly, encourage the fainthearted, help the weak, be patient with everyone. See that no one repays another with evil for evil, but always seek after that which is good for one another and for all people. Rejoice always; pray without ceasing; in everything give thanks; for this is God's will for you in Christ Jesus. Do not quench the Spirit; do not despise prophetic utterances. But examine everything carefully; hold fast to that which is good; abstain from every form of evil. Now may the God of peace Himself sanctify you entirely; and may your spirit and soul and body be preserved complete, without blame at the coming of our Lord Jesus Christ. Faithful is He who calls you, and He also will bring it to pass.
