Jeremiah was writing of Jerusalem and the situation of the Jews in Lamenations, but these verses in chapter 3 always touch my heart in their absolute truth for us and if you will consider this first verse as it will apply to those who receive a love of the truth after the Rapture, maybe even because of the [truth of the] Rapture:
22 It is of the LORD's mercies that we are not consumed, because His compassions fail not.
23They are new every morning: great is Thy faithfulness.
24The LORD is my portion, saith my soul; therefore will I hope in Him.
His compassions will not fail those who are left behind because He has taken His Church home. He is still there to find. He remains merciful, and to anyone who calls on Jesus Christ for salvation as a sinner, they will be saved, and every day, He renews His mercy. He is faithful doing this for our benefit. He is our portion, and for those left behind, He is their portion as well, and He is the only hope and has always been.
I feel sorry for those, even those professing Christians, who keep thinking there is another answer besides Jesus, who leave the simplicity which is Christ. Jesus is truth, in all things. In Acts 17:26, when Paul is in Athens he talks about how every person has been born into preappointed times and boundaries by the Lord in order that each (v27) should seek the Lord in the hope that they might grope for Him and find Him though he is not far from each one of us....It is no mistake where we are in time, and it is no mistake that those who come to salvation when the Lord takes His Church home are where they are either. This speaks of a soverign God who knows every detail of His creation placing us in time with boundaries that we might find Him. That is beautiful, and all things are with this end--that we might find Him and be saved--and that He is glorified by all things. Oh, how He loves us!
