But a time is coming, and it is already here! Even now the true worshipers are being led by the Spirit to worship the Father according to the truth. These are the ones the Father is seeking to worship him. (John 4:23 Contemporary English Version)

¹I APPEAL to you therefore, brethren, and beg of you in view of [all] the mercies of God, to make a decisive dedication of your bodies [presenting all your members and faculties] as a living sacrifice, holy (devoted, consecrated) and well pleasing to God, which is your reasonable (rational, intelligent) service and spiritual worship. ²Do not be conformed to this world (this age), [fashioned after and adapted to its external, superficial customs], but be transformed (changed) by the [entire] renewal of your mind [by its new ideals and its new attitude], so that you may prove [for yourselves] what is the good and acceptable and perfect will of God, even the thing which is good and acceptable and perfect [in His sight for you]. (Romans 12:1-2 Amplified Bible)

Spiritual enough already you are as God's worshipers. The truth still needs you to be reasonable and rational.

Does Trinity ever sound reasonable to you? Is it derived from biblical truth? Or you simply have no idea how to answer the previous 2 questions but merely conforming to this world of mainstream Christianity religion - human tradition?
