It is exceptionally hard to do ... I remind myself that the Lord wept over His own beloved city ... did what He had to do on Calvary, and LEFT ... told folks living there: "Don't weep for me; weep for yourselves and your children." He knew what was coming ... and STILL LEFT ... so He could get home and send the Holy Spirit and thus be with all those who believe in Him. So, if it was necessary for HIM to stay on mission and stop doing all the things that could have forever have been done for those in physical need, it is most definitely necessary for us.
