The Psalmist says that workers of deceit will not dwell in His house. Psalm 101 is fulfilled in Jesus, and so He sings these words to His Father as He reigns now in glory, putting all of His enemies beneath His feet.
So how shall we stand in His presence? How can we sit here in His house given that we have sinned, that we have lied, that we have loved the world and the things of the world rather than loving God as we ought?
Well the answer has everything to do with how you receive the admonition, how you receive the warning. If you sit there in your seat rolling your eyes and wondering how long till the service is over, hurry it up preacher boy, well then, this Psalm is talking about you. Jesus hates your lies, your froward heart, your proud eyes, and you will not remain here long like that.
But if you know that you have lied, that you have been proud, that you have joined with the wicked in their deeds, and you hate it. It burns you, it burdens you, it weighs you down, and if you confessed it, cried out to God for it, sought His deliverance for it, and though you have failed many times. Every time you come back desperate for grace, there is another cup of mercy full to the brim for you.
The grace of God is spread before you: the broken body of Jesus and His shed blood for your sins, to make you whole. When you eat and drink and trust in Him, you are covered in His righteousness, His obedience. You are covered in His glory. You belong here in His house, and by His wonderful grace you become one of the faithful in the land, walking in the perfect way, and a minister of His mercy for the world.
So come, eat, drink, and rejoice.
