What more could He do?

Just got done listening to a message from oldpathsermons.com, the text was Isaiah chapter 5. The message deals with some things that have been on my heart and mind lately.

Isaiah 5
1 ¶ Now will I sing to my wellbeloved a song of my beloved touching his vineyard. My wellbeloved hath a vineyard in a very fruitful hill:
2 And he fenced it, and gathered out the stones thereof, and planted it with the choicest vine, and built a tower in the midst of it, and also made a winepress therein: and he looked that it should bring forth grapes, and it brought forth wild grapes.

These verses talk about how a vineyard was planted, how great care was taken to make sure the vineyard would have every opportunity to produce. The verse talks about how the vineyard was fenced, it was protected from intruders and wild animals that might come in and harm the vineyard. It talks about how the stones were gathered out, about the tower that was built in the midst of it, and how he placed a winepress in the vineyard.
What is the purpose of the winepress? So wine could be made when the vines have produced their fruit. This vineyard was not planted simply for show, for people to walk by and say, "what a beautiful vineyard". This vineyard was expected to produced fruit so the owner would have something to show for his hard work of building, working, and caring for this vineyard. But verse two tells us that when it should have brought forth grapes, it brought forth wild grapes. Grapes that were good for no use at all.
We know from John chapter 15 that God is the husbandman, Jesus is the vine, and we are the branches. We are to bare fruit for the masters work. I'm afraid, however, that just like Isaiah chapter 5 when God has expected to reap grapes from our lives we have given Him nothing but wild grapes.

4 What could have been done more to my vineyard, that I have not done in it? wherefore, when I looked that it should bring forth grapes, brought it forth wild grapes wherefore, when I looked that it should bring forth grapes, brought it forth wild grapes?

So the question is, what more could he do? What more could the Lord do for us to get us to produce fruit for His glory? We live in the greatest country on earth, we live without threat of persecution. We have beautiful church buildings, but we do not have the power of God in our hearts, and homes, and at the house of God. We have allowed this world to consume our lives and anything that has any resemblance to God is chocked out.
What happened to Christians living separated from this world. Not because it's popular, not because the preacher preaches it, and not even because the bible say so, but because we want to please HIM. Why do we have to have fifteen verses on something before we are willing to give it up for the Lord? Why can't we say, "Lord, I don't know if this is wrong or not, but there's so much controversy surrounding it that I'm going to give it up because I want to please you". What more does the Lord have to do for us to get us to serve Him? What's it going to take in your life and mine for us to sell out to God?
What more could He do?
