Look at all the work it takes to remain undefiled or pure before God in Numbers 19. But now, all we need is to accept Christ our Lord Jesus as our Savior and we are holy and righteous forever. How kooooooooooool is that. So before you complain about that next little temptation you have to overcome, consider all the Israelites had to go through to stay pure and then all our Lord Christ Jesus suffered to obtain purity for us.
Hebrews 9:11-15a
11 So Christ has now become the High Priest over all the good things that have come. He has entered that greater, more perfect Tabernacle in heaven, which was not made by human hands and is not part of this created world.
12 With his own blood—not the blood of goats and calves—he entered the Most Holy Place once for all time and secured our redemption forever.
13 Under the old system, the blood of goats and bulls and the ashes of a young cow could cleanse people’s bodies from ceremonial impurity.
14 Just think how much more the blood of Christ will purify our consciences from sinful deeds so that we can worship the living God. For by the power of the eternal Spirit, Christ offered himself to God as a perfect sacrifice for our sins.
15 That is why he is the one who mediates a new covenant between God and people, so that all who are called can receive the eternal inheritance God has promised them
