"For you are not a God who delights in wickedness;
evil may not dwell with you.
The boastful shall not stand before your eyes;
you hate all evildoers.
You destroy those who speak lies;
the LORD abhors the bloodthirsty and deceitful man.
But I, through the abundance of your steadfast love,
will enter your house."
Only through the steadfast love of God is man able to enter His house. Not by works or good conscious. If evil may not dwell with God, and He destroys those who lie, that leaves every man completely dependent upon an act of God's grace. Because we have all rebelled, we deserve to be outsiders. But this is where it gets interesting. Jesus Christ, the 2nd person of the trinity came to earth, became an outsider, took upon himself the just punishment for all of God's people, for their evil and rebellious hearts, and for every lie spoke. Now, those who trust in Christ may enter His house. Only through the abundance of God's steadfast love can we enter His house. The Apostle John captures how the Cross is the manifestation of this steadfast love. God has ultimately made a way for wrath deserving sinners to come to Him and dwell in His house.
"In this the love of God was made manifest among us, that God sent his only Son into the world, so that we might live through him. 10In this is love, not that we have loved God but that he loved us and sent his Son to be the propitiation for our sins."
1 John 4:9-10
