The religious services, the prayers, the praise, the penitent confession of sin, ascend from true believers as incense to the heavenly sanctuary: but passing through the corrupt channels of humanity, they are so defiled that unless purified by blood, they can never be of value with God. . . . All incense from earthly tabernacles must be moist with the cleansing drops of the blood of Christ. He holds before the Father the censer of His own merits, in which there is no taint of earthly corruption. He gathers into this censer the prayers, the praise, and the confessions of His people, and with these He puts His own spotless righteousness. Then, perfumed with the merits of Christ's propitiation, the incense comes up before God wholly and entirely acceptable. . . . {AG 154.4}
O, that all may see that everything in obedience, in penitence, in praise and thanksgiving must be placed upon the glowing fire of the righteousness of Christ. {AG 154.5}
