2 Peter 3:12 mentions our ability to "speed the coming of the day of the Lord," which suggests our shirking our duties to the Master who bought us with his own blood actually delays his coming. Could the tears in heaven be realizing fully what we missed out on by going whole-heartedly into the Christian faith with everything we have?
Think of it, if every believer submitted to God and applied themselves fully and only to spreading his Gospel, his return would not have been delayed so long. Since God knows who will believe since before there ever was an earth... he apparently "seeds" them into the portion of history that they will receive the best witness for them to believe on the Lord Jesus Christ. We we fully devoted to him, he wouldn't have needed to prolong history and perhaps within a few generations all believers would have been born.
Now the bad news.
If this is true...
Notice, folks, I said " I F "
If this is true then to perpetuate human history, millions of unsaved people who would never believe had to be born. That means millions and millions of lives in hell that would never had to be born in the first place if believers in Jesus Christ were fully devoted to Christ rather than self, the world, things and people in the world.
It's high time we asked ourselves these tough questions, faced the music, and lay down the rest of our lives for the Lord God who laid down his life for us and took it up again so that we could be with him in eternity.
I F ... this all is true, then the crying will be over the spilled blood and innocent lives our irresponsibility and selfishness cost.
You worry about babies... everyone of them were babies...
Weep and wail for them and for the LORD who had to settle for our least when he gave his best... then the tears will flow like rivers and streams... and even this (again if true) he will forgive us for and put out of our minds (Revelation 21:4) because that is how wonderful he is!"
