Ezekiel 43:13 -27
These are the measurements of the altar in cubits (the cubit is one cubit and a handbreadth): the base one cubit high and one cubit wide, with a rim all around its edge of one span. This is the height of the altar: 14 from the base on the ground to the lower ledge, two cubits; the width of the ledge, one cubit; from the smaller ledge to the larger ledge, four cubits; and the width of the ledge, one cubit. 15 The altar hearth is four cubits high, with four horns extending upward from the hearth. 16 The altar hearth is twelve cubits long, twelve wide, square at its four corners; 17 the ledge, fourteen cubits long and fourteen wide on its four sides, with a rim of half a cubit around it; its base, one cubit all around; and its steps face toward the east.”
18 And He said to me, “Son of man, thus says the Lord GOD: ‘These are the ordinances for the altar on the day when it is made, for sacrificing burnt offerings on it, and for sprinkling blood on it. 19 You shall give a young bull for a sin offering to the priests, the Levites, who are of the seed of Zadok, who approach Me to minister to Me,’ says the Lord GOD. 20 ‘You shall take some of its blood and put it on the four horns of the altar, on the four corners of the ledge, and on the rim around it; thus you shall cleanse it and make atonement for it. 21 Then you shall also take the bull of the sin offering, and burn it in the appointed place of the temple, outside the sanctuary. 22 On the second day you shall offer a kid of the goats without blemish for a sin offering; and they shall cleanse the altar, as they cleansed it with the bull. 23 When you have finished cleansing it, you shall offer a young bull without blemish, and a ram from the flock without blemish. 24 When you offer them before the LORD, the priests shall throw salt on them, and they will offer them up as a burnt offering to the LORD. 25 Every day for seven days you shall prepare a goat for a sin offering; they shall also prepare a young bull and a ram from the flock, both without blemish. 26 Seven days they shall make atonement for the altar and purify it, and so consecrate it. 27 When these days are over it shall be, on the eighth day and thereafter, that the priests shall offer your burnt offerings and your peace offerings on the altar; and I will accept you,’ says the Lord GOD.”
Have we as believers, burnt our past, our idols, our former beliefs on the altar of the cross? Burnt is destroyed, changed to unusable, gone. Christ made it possible but we have to give them up; not take them up. We are changed at the cross to new life, do we really believe what we believe is really real?
