I've been thinking.
Actually I've been watching videos, but when listening to the above song I began to weep just awed by God's power and Christ's love. Then the song goes into (what I believe is called) the bridge;
"and we will overcome, by the blood of the lamb and the word of our testimony"
Naturally, my weeping subsided because the focus of the song shifted towards what I'm supposed to do. Rather than the intrinsic thanksgiving towards God.
I'm not going to lie, I was a little inconvenienced, I was enjoying my moment of personal worship. Then I began to realize that I'm not just supposed to let myself be moved and then not do anything, even in light of what God did for me.
One of the things that I've started to notice is a radical difference in what Biblical Love and Wordly Love mean. Wordly Love has taken a stab at being a steadfast love, but has changed to be a love that loves despite imperfections. Biblical love is this as well, but Worldly Love is love that is static, love that never expects change.
Biblical Love bears some vague semblance, but true Biblical love is a love that loves towards a goal, love that expects action, loves that does not force, but a love so pure and wholesome that the only response is action, obedience.
This is God's love for us: (Rom. 5:8) that even while were sinner's Christ died for us, and (Rom. 2:4) that God's kindness is meant to lead us to repentance.
This is God's mode of love (John 3:16) for God so love the world, that he sent his only son that those who believe will have everlasting life. God's love caused him to act, and if we aspire to be like Christ and as we are in God's very image, our love for God and others should spur us into action.
Here is where the response comes in. Are we really letting God's love move us, if we weep, jump, pray and praise in times of worship and are comforted, why shouldn't pass that on?
Paul is expressly clear in II Corinthians 1:2-7: (I'll paraphrase for brevity's sake) God comforts us so that we can comfort others, again, a response...
What can we do, well unless God has been putting something specific on your heart to do, someone to serve or even pray for... do it!
Heck if nothing specific, just pray for the people around or pray for opportunity to pass the comfort, love and blessing on, I guarantee he will give you an opportunity.
