(2) Christianity teaches that human is a heavenly creature:
Heaven for us is the final destiny, and the ultimate goal to achieve. The heavenly kingdom is the real treasure we demand to gain. It is our original final home for the permanent presence with God. Hence we feel that we are sojourners in this world, which will vanish, seeking Him only. Therefore, we put all our desires to return to our heavenly homeland. The New Testament confirmed this fact... as St. Paul the Apostle says, “These all died in faith, not having received the promises, but having seen them afar off were assured of them, embraced them and confessed that they were strangers and pilgrims on the earth. For those who say such things declare plainly that they seek a homeland” (Hebrews 11:13, 14). He writes to the Corinthians saying, “So we are always confident, knowing that while we are at home in the body we are absent from the Lord. For we walk by faith, not by sight. We are confident, yes, well pleased rather to be absent from the body and to be present with the Lord” (2 Corinthians 5: 6-8)

(3) Christianity teaches that a man must direct his desires toward the heaven:
St. Paul writes to the Colossians encouraging them by saying, “…because of the hope which is laid up for you in heaven, of which you heard before in the word of the truth of the gospel” ( Col 1: 5). In this sense, the Apostle Paul writes, “For our citizenship is in heaven, from which we also eagerly wait for the Savior, the Lord Jesus Christ” (Philippians 3:20). He also says to the Colossians, “If then you were raised with Christ, seek those things which are above, where Christ is, sitting at the right hand of God. Set your mind on things above, not on things on the earth” (Col 3: 1, 2). Based on the fact that man is a heavenly creature and his Father is in the heaven, he converse with his heavenly Father in prayers, and offers his alms knowing that he is treasuring it into heaven (Matthew 6:19, 20). And he asks the intercessions of the angels and the saints who preceded him to heaven. Even more than that, his soul will be wed into the heavenly wedding. Because of all these sacred feelings and believes, the holy confessors and martyrs were very pleased during their imprisonment.

The main purpose of the emperors and kings behind the imprisonment of the confessors Christians is to destroy their courage and weaken their morale. But, on the contrary, this increased their courage.

It is beyond imagination and exceeds natural capability of human beings that sorrows create joy, and afflictions generate comfort. But Christianity, through the divine grace, i.e. the work of the Holy Spirit in believers, is doing it. The reasons for this are:
1. Divine support promised by God to all those who are persecuted for his name (Luke 21: 12-19).
2. Looking forward in faith to the great glory that awaits them, and that the Lord Jesus will wipe away every tear from their eyes (Revelation 21: 4).
3. Sympathy for them by the church - with all its members as a single body - whether through prayers for them or physical care for the concerns and needs of their families.
4. Glorious visions that have been announced to them, which had the greatest impact in encouraging them. Therefore, the prison in their eyes became a door for the heaven!

So the confessors in prisons were full of peace. They were in a hurry for their trial date, not for the possibility of release. They considered their trials before the rulers to be their share with the Lord Jesus during His trial before Pontius Pilate.

The high morale and the Christian courage are reflected in the dialogues that took place between them and their judges... Those confessors had only one response when they were questioned, which remained heard for nearly three centuries in the courtyards across the Empire. This answer is “I am a Christian (Christian us Sum).” The cry of the raging people who was tracking this recognition is, “Death to Christians.”

All their thought was focused on their desire to get out from this present world to eternal inheritance, rejoicing for the crowns prepared for them by the Lord; and to join all those who preceded them of the martyrs and the saints to live with them eternally.

We are still surrounded by so great a cloud of these martyrs to this day; and they are interceding before Christ for us, their brethren, to complete our struggle.
