Some of us talk a lot about the Gospel and criticise legalism. We rejoice a lot in what God has done in the cross of Christ, but less in Christ himself. The Gospel, or perhaps more commonly 'grace' is abstracted and made into a principle or scheme. We are not very good at saying what we are saved to, or who we are reconciled to. We are good at talking about redemption, but not revelation. We should rejoice more in the person of Christ, not just because of what he has done.
Some of us talk a lot about Jesus and criticise monster-God alternatives. We rejoice a lot in who God is, but are remarkably uninterested in what he has done. Jesus becomes a cipher or an idealised God-as-I'd-like-him and not a real person who acts and interacts with us in our fallen state. We are are not very good at saying that we are saved or reconciled and God is being offered as a nice option on the menu we can freely choose. We are good at talking about revelation, but not redemption. We should rejoice more in the work of Christ, not just because it shows us who he is.
I wish I could say that better than I have... I say 'we' in the post because I am always overbalancing one way or another, but lets be people who rejoice in the person and work of Christ (which, incidentally, saves us from both the power and the penalty of sin)
