Hebrews 12:23-25 New International Version - UK (NIVUK)
23 to the church of the firstborn, whose names are written in heaven. You have come to God, the Judge of all, to the spirits of the righteous made perfect, 24 to Jesus the mediator of a new covenant, and to the sprinkled blood that speaks a better word than the blood of Abel.
25 See to it that you do not refuse him who speaks. If they did not escape when they refused him who warned them on earth, how much less will we, if we turn away from him who warns us from heaven?
