On the eve of His death, standing in the shadow of Calvary, Jesus takes time to encourage His Disciples. Were their hearts troubled? Indeed they were. He has just told them of His impending death.
John 14:1-3 Let not your heart be troubled: ye believe in God, believe also in me. In my Father's house are many mansions: if it were not so , I would have told you. I go to prepare a place for you. And if I go and prepare a place for you, I will come again, and receive you unto myself; that where I am, there ye may be also.
Thank God, there is hope for tomorrow. The preparation for a place in the Heavenly City is for all believers. We will dwell in the Father’s House with the Father and His Son Jesus. We will be free from sin, sorrow, and suffering.
Try as I might, I could never adequately describe the glories of that place. I think Paul summed it up pretty well.
1 Corinthians 2:9 But as it is written, Eye hath not seen, nor ear heard, neither have entered into the heart of man, the things which God hath prepared for them that love him.
