To worship God 'in spirit and in truth' is first and foremost a way of saying that we must worship God by means of Christ. In him the reality has dawned and the shadows are being swept away (Hebrews 8:13). Christian worship is new covenant worship; it is gospel-inspired worship; it is Christ-centered worship; it is cross-focused worship.
D. A. CarsonThere is no long-range effective teaching of the Bible that is not accompanied by long hours of ongoing study of the Bible.
D. A. CarsonWhen Christians speak of the authority of Scripture, because Christians believe that this word, even though it's mediated through many different human authors, nevertheless is God breathed and is revealed by God and is utterly reliable and all that it says, with all of its different literary genres, it's trustworthy and without mistake or distortion. It is trustworthy and therefore, because it is from God it has God's authority.
D. A. CarsonIt's not a matter of us standing outside it and ticking off the boxes: yes, the Bible is faithful here; yes, it's telling the truth there, and so on, but rather granted that it's God-given. It's the frame of reference that shows us how to live in, tells us how to think about everything.
