Therefore, now, no condemnation for those who are in Messiah, Jesus! (Romans 8:1)
It is a plain and forceful cry. No condemnation for sinning, struggling Christians who yearn to be rescued from their...frustration and failure! The only thing that will strengthen you to keep fighting is God's strong assurance of grace. Paul's whole point in this verse is to speak peace into the storm of our souls, calming our inner turmoil...
So who may allow himself to breathe in the good news' atmosphere of gracious acceptance? 'Those who are in Christ Jesus' - period. You may or may not be walking in the Spirit at any given moment. But there is no condemnation for you, none at all - not because your behavior is so Christian but because your Savior is Christ.
And this is true for you right now.
'There is therefore now'...Not five years from now, when you hope you are a better Christian, but right now, as you are, Jesus Christ is your absolute Savior.
