When we worship God in spirit and truth, this kind of worship is not with our bodies (our raised arms and hands, or bended knees, or praying hands, or dancing bodies, or musical instruments, or the songs we sing during a worship service). All of that kind of worship is the sensuous (the Old Testament’s way of worshipping God, which is outwardly and earthly). Under the New Testament’s covenant of Grace, believers in Christ worship God in a true and spiritual way, in particular inwardly and heavenly.
Love doesn’t get any nobler than agápe. There is no doubt that agápe is the highest kind of love there is. No other type of earthly love can come close to God’s unconditional, self-denying, long-suffering, kind, and supportive type of love.
Of the four types of love addressed in the New Testament, God’s agápe love is the kind of love He commands us to demonstrate. To make sure that we indeed could fulfill the command to love with the agápe kind of love, which God and Jesus Christ gave to us, Father God gave us His Holy Spirit, and His Holy Spirit then poured into our hearts/spirits the unconditional love of God.
