'The life which I know live in the flesh I live by faith in the Son of God, who loved my an gave Himself for me'
Paul wants us to know that the only way to for God is by faith. And that faith needs to be faith in the gospel. It's faith in the fact that the God-man was slaughtered in my place and for my sin. But not only that. Paul also wants us to know that His bloody death is the greatest indicator of God's love. Jesus death means God's love. But not only in a general sense. We need to have an impression of His love on our hearts. We need to see and be amazed that He gave Himself for us and you individually. We need to see that God's love is wonderfully personally and beautifully individual, whilst being at the same time collective.
So according to Paul the Christian life is empowered by a realisation of God's love shown in Jesus. If I'm to do anything Christian in my life- if I'm to love my neighbour, help the poor, serve my city, kill sin- I need to believe the gospel to greater degree everyday. The extent to which I believe the gospel is the extent of the empowering I receive to live God's way.
My resolution for 2010 and (continuing resolution for every year to come) is reflected in Ephesians 3:17-19
'that Christ may dwell in your hearts through faith; that you, being rooted and grounded in love, may be able to comprehend with all the saints what is the width and length and depth and height— to know the love of Christ which passes knowledge; that you may be filled with all the fullness of God.'
