From Deut. 12, did you notice the JOY? This one place that the Lord will establish where our worship is to be offered? "There you shall eat before the Lord, and you shall rejoice." "And you shall rejoice before the Lord your God." This "place" for us is the Table of the Lord which is now set up throughout the world. And as we gather before that place to bring to Him of what He has given to us so that He can give back infinitely more than we offer to Him of what was already His own, He brings joy to our hearts. Worship is the fount of joy - from it comes the joy that is lasting - this joy of "eating before the Lord" or with the Lord or actually eating the Lord Himself, shocking as that sounds. Joy overflowing indeed!
On the second reading from Matthew 12, is it not absolutely striking how the Lord Jesus, when speaking of the blasphemy against the Holy Spirit, makes it utterly clear that the Holy Spirit is a PERSON? Sasse once said that you might get the impression from the rest of the NT, absent John 14-17, the farewell discourse, that the Spirit was but a force or power of God. But you can't sin against a force, you can't sin against a power. You can only sin against a Person.
