God is a Spirit: and they that worship Him must worship Him in spirit and in truth.
In the verse prior to our verse today God is seeking worshippers. The seeking of God here expresses the longing of God’s heart for one who truly worships Him - one who willingly gives from the heart because he is thankful for what he has been given, one who worships from a heart full of love for God, one who is so overcome with God’s work of salvation that praise just flows from his mouth. Worship in spirit and in truth is in contrast to ritual and formality. Daily sacrifices, offerings of incense, tithing, observance of the law and regular attendances at the temple could all be done without a true heart for God. God longs for the true worship of your heart today.
