For if that first [covenant] had been faultless, then should no place have been sought for the second.
This chapter Hebrews 8 makes it very clear that the old ways of the human priests offering gifts and sacrifices according to the law, and the creation and building of the tabernacle, is old, faulty, decayed, and ready to vanish away.v13
In that he saith, A new [covenant], he hath made the first old. Now that which decayeth and waxeth old [is] ready to vanish away.
Instead, the old covenant has been replaced by the new covenant of Christ our high priest, a heavenly sanctuary, and the Lord's new law, written on our hearts. We should no longer try to live under the antiquated ways, but we should rejoice in the liberty of forgiven life in the merciful Christ.v12
For I will be merciful to their unrighteousness, and their sins and their iniquities will I remember no more.
