Heavenly sign for unbelievers

Annually on the first Sunday after the Easter in all the orthodox churches is read the Gospel of John, in which we see how the resurrected Christ appeared to his disciples. Apostle Thomas was absent at that time, that is why he did not believe in the resurrection of Christ: "Unless I see in his hands the mark of the nails, and place my finger into the mark of the nails, and place my hand into his side, I will never believe!" He disbelieved, although he saw many wonders in the time of Jesus' life: how Jesus turned water into wine, fed the 5 thousand people, walked on water, numerous healings of people according to their faith.
