How bad was the persecution of Christians in the 1st century?

Acts 8:1-3
And there arose on that day a great persecution against the church in Jerusalem, and they were all scattered throughout the regions of Judea and Samaria, except the apostles. 2 Devout men buried Stephen and made great lamentation over him. 3 But Saul was ravaging the church, and entering house after house, he dragged off men and women and committed them to prison.

Acts 12:1-3
About that time Herod the king laid violent hands on some who belonged to the church. 2 He killed James the brother of John with the sword, 3 and when he saw that it pleased the Jews, he proceeded to arrest Peter also.

Revelation 6:9
When he opened the fifth seal, I saw under the altar the souls of those who had been slain for the word of God and for the witness they had borne.

Why do you think the speaker feels so strongly about his statement: “When we belittle the word PERSECUTION down to annoyances, we diminish the sacrifice of those persecuted.”? Do you see a progression in magnitude in the words below?

2 Corinthians 12:10
For the sake of Christ, then, I am content with weaknesses, insults, hardships, persecutions, and calamities. For when I am weak, then I am strong.

How can persecution lead to maturity?

James 1:2-4 (Easy-to-Read Version, Revised Edition)
My brothers and sisters, you will have many kinds of trouble. But this gives you a reason to be very happy. 3 You know that when your faith is tested, you learn to be patient in suffering. 4 If you let that patience work in you, the end result will be good. You will be mature and complete. You will be all that God wants you to be.

Whether in weakness, insult, hardship, persecution, or calamity, how does Christ ask Christians to respond?

Matthew 5:10-12
“Blessed are those who are persecuted for righteousness’ sake, for theirs is the kingdom of heaven.
11 “Blessed are you when others revile you and persecute you and utter all kinds of evil against you falsely on my account. 12 Rejoice and be glad, for your reward is great in heaven, for so they persecuted the prophets who were before you.

Matthew 5:44-46
But I say to you, Love your enemies and pray for those who persecute you, 45 so that you may be sons of your Father who is in heaven. For he makes his sun rise on the evil and on the good, and sends rain on the just and on the unjust. 46 For if you love those who love you, what reward do you have? Do not even the tax collectors do the same?

Luke 21:12-13
But before all this they will lay their hands on you and persecute you, delivering you up to the synagogues and prisons, and you will be brought before kings and governors for my name’s sake. 13 This will be your opportunity to bear witness.

John 15:20-21
Remember the word that I said to you: ‘A servant is not greater than his master.’ If they persecuted me, they will also persecute you. If they kept my word, they will also keep yours. 21 But all these things they will do to you on account of my name, because they do not know him who sent me.

What promises does Christ give us if we live faithfully in the face of persecution?

Romans 8:35-39
Who shall separate us from the love of Christ? Shall tribulation, or distress, or persecution, or famine, or nakedness, or danger, or sword? 36 As it is written, “For your sake we are being killed all the day long; we are regarded as sheep to be slaughtered.” 37 No, in all these things we are more than conquerors through him who loved us. 38 For I am sure that neither death nor life, nor angels nor rulers, nor things present nor things to come, nor powers, 39 nor height nor depth, nor anything else in all creation, will be able to separate us from the love of God in Christ Jesus our Lord.

1 Peter 4:12-14
Beloved, do not be surprised at the fiery trial when it comes upon you to test you, as though something strange were happening to you. 13 But rejoice insofar as you share Christ’s sufferings, that you may also rejoice and be glad when his glory is revealed. 14 If you are insulted for the name of Christ, you are blessed, because the Spirit of glory and of God rests upon you.

Revelation 2:10-11
Be faithful unto death, and I will give you the crown of life. 11 He who has an ear, let him hear what the Spirit says to the churches. The one who conquers will not be hurt by the second death.’
