what is obsolete and aging will soon disappear

God made for us a new covenant in Christ.
"This is the covenant I will make with the house of Israel
after that time, declares the Lord.
I will put my laws in their minds
and write them on their hearts.
I will be their God,
and they will be my people.
"No longer will a man teach his neighbor,
or a man his brother, saying, 'Know the Lord,'
because they will all know me,
from the least of them to the greatest.
"For I will forgive their wickedness
and will remember their sins no more."
I read this passage in Hebrews 8 yesterday and it struck me. This quotation that the author used shows a definitive break point from the old covenant with the Jews. It's amazing, to me, to think that God said he would write it on our hearts--we don't need to tell each other about it; you don't need to sharpen it and hold it over your neighbor's head! I can't wait till that day when we will, indeed, all know the Lord! And finally, our wickedness forgiven! Remember our sins no more--what a prospect! My only question is whether this covenant is what has already been established by Jesus' death and resurrection, or will it be brought in by the second coming? The passage goes on...
"By calling this covenant "new," he has made the first one obsolete; and what is obsolete and aging will soon disappear."
It is explicitly set in present tense, showing that it's already done! He HAS made it obsolete. It is no more. It is our utmost joy that we don't have to wait for that forgiveness, for that covenant to pass on: it's obsolete! I really don't know what to add...
On a more worldly note, today, I had the chance to go back to Houghton and see who's there on mayterm or just hanging out and working. I loved catching up with those people--something I do so much better in person then over the internets here. I even got to see my roommate one last time before we each go our ways. My visit has given me the new desire to be back at school and see eveyone again, but that's still three months off...it's a good anticipation, I guess.
It' sbeen a long day and I still have some reading to do if I'm gonna get through my books before Sunday, so I'm off!
