Is it a cry to those who already know the Lord but who have wandered away? rejected God? couldn't be bothered? are angry at God? To whom is the psalmist or prophet speaking?
But here is an even more disquieting question: is this a cry of longing? Or, could this be a veiled threat? Is God pleading with God's beloved to come home again, or is there an implied punishment for continuing to ignore God's call?
I have a sneaking suspicion that those whose relationship with God is weak, or stale or even non-existent hear this cry to 'return to the Lord' as threat. My conclusion comes from those conversations I have with folks who want me to justify the constant judgmental behavior of Christians. Once they have run through all their experiences (real or via facebook) with those kind of Christians, they want to take on the concept of commandments that need to be followed. It doesn't often occur to these folk that they are hearing the 'Fox News' version of God; not the God I know at all.
After all that conversation, in the end, I believe that what they really want - no, what they need - is absolution for their broken places and an assurance that they are loved. Not that they would put it that way, but I'm a pastor and that's how I think.
Of course they need to return to the Lord to receive those things. Unconditional love, absolution for their broken places: these are the purview of God and God's free gifts to those who turn towards God. They will have to turn their faces towards the light of the Creator to catch a glimpse of this God who we know as a lover and a friend, a forgiver and redeemer. It is not necessary to join a convent, just turn towards God so you can catch the work of the Spirit in your life or
so you can catch the life that is in the work of the Spirit.
That's the heart of it, isn't it? God's work is the work of life, offered in love, for the sake of those whom God loves..........and who doesn't God love? Return to the Lord your God. It's safe. God's been watching and waiting forever to welcome you home.
