Is this still true of Christians today?

"As first-century skeptics and seekers read Acts, those who sincerely sought the truth came to better understand God’s way. Many no doubt followed that way."

That's how the quote ends.  When I read it, I couldn't help but wonder -- if people looked at us (Christians) today, would they come to the same conclusion?  When they look at us, what do they think is "God's way"?  Furthermore, is what they see something they'd want to follow?

Here's the whole paragraph from which the leading sentences were drawn -

"Pagan Romans may have felt that Christianity threatened the peace of society. Luke wrote for these skeptics, too. He points out that the Christians do nothing to harm life and do much to help it. The God who made and who loves the world is behind … better yet, is in … the Christians. God, through them, wishes to give His peace to all people. As first-century skeptics and seekers read Acts, those who sincerely sought the truth came to better understand God’s way. Many no doubt followed that way."

So, where does this paragraph come from?  It's from About Acts: A Bible Commentary in the Wesleyan Tradition.

You may or may not be aware, but Christianity did "conquer" Rome - in a sense.  Not a military battle, but a battle in the way Jesus and Paul said it really is -

From Jesus, we learn that His Kingdom, and the real battle, are not of this world.  

Jn 18:36 Jesus said, “My kingdom is not of this world. If it were, my servants would fight to prevent my arrest by the Jews. But now my kingdom is from another place.”

And from Paul, we read more specifics -

2Co 10:3 For though we live in the world, we do not wage war as the world does. 4 The weapons we fight with are not the weapons of the world. On the contrary, they have divine power to demolish strongholds. 5 We demolish arguments and every pretension that sets itself up against the knowledge of God, and we take captive every thought to make it obedient to Christ. 

And finally, this -

The Armor of God

Eph 6:10 Finally, be strong in the Lord and in his mighty power. 11 Put on the full armor of God so that you can take your stand against the devil’s schemes. 12 For our struggle is not against flesh and blood, but against the rulers, against the authorities, against the powers of this dark world and against the spiritual forces of evil in the heavenly realms. 13 Therefore put on the full armor of God, so that when the day of evil comes, you may be able to stand your ground, and after you have done everything, to stand. 14 Stand firm then, with the belt of truth buckled around your waist, with the breastplate of righteousness in place, 15 and with your feet fitted with the readiness that comes from the gospel of peace. 16 In addition to all this, take up the shield of faith, with which you can extinguish all the flaming arrows of the evil one. 17 Take the helmet of salvation and the sword of the Spirit, which is the word of God. 18 And pray in the Spirit on all occasions with all kinds of prayers and requests. With this in mind, be alert and always keep on praying for all the saints.

In the world today, we want to fight evil with guns, bombs, drone strikes, the "mother of all bombs", and whatever kind of military firepower we can come up with.   And while it's true they didn't have any of these weapons back in the first century - it's not true that they were without weapons at all.  The Roman army on Jesus' time was the most brutal army that had ever existed, up to that time.

War, in the time of the early church

To give some idea of how war was viewed by the Roman government, see this -

Roman Warfare in New Testament Times (27 BC–AD 198)
At the time of Christ’s birth, Rome had transitioned from a republic to an autocracy with professional armies. The government was called the “Principate,” named after the princeps (“first citizen”)—the emperor. The emperors of the Principate legally established the first-century BC practice of requiring all soldiers to take an oath to the emperor. The emperor Severus (AD 193–211) reportedly instructed his heir Caracalla to “Be harmonious, enrich the soldiers, and scorn all other men” (Cassius Dio, 77.15).  ¹Brand, S. (2016).
