Psalm 121: Coming and Going

I often conflate the coming and going of this psalm, when offering this blessing during baptism. I'm trying to convey the idea that we come into God's house by his blessing, and leave to be a blessing to others. Jesus came to save. He sends us saved ones to save others. We don't just come into the place of God's grace. As long as we live we also go as his ambassadors to offer grace and truth to others - the same grace and truth we have received from God.  May your coming in and your going out be blessed from this time forth and forevermore!
