Romans 8 is perhaps the most comforting passage in all of Scripture for me. It reminds me who I am and who God is. It tells me what the Holy Spirit is doing and what Christ as done. It shows me that I belong to God - and He fights for me and blesses me and gives to me. He loves me. It challenges me in light of these things to battle my sin and conquer. It consoles me in that it affirms that through Christ I am already a conqueror. It says, "Kill your sin," and when I fail as I so often do, it says, "You are free. There is no condemnation for you."
And in light of these things, we can take heart that there is nothing in this world or the next that can sever us from God's presence or separate us from His love. Our God is for us!
