(Paul was stirred up to attempt to preach the gospel for Jesus, at the wildest place in the main city of Athens:)
Acts 17:15 And they that conducted Paul brought him unto Athens: and receiving a commandment unto Silas and Timotheus for to come to him with all speed, they departed.
16 Now while Paul waited for them at Athens, his spirit was stirred in him, when he saw the city wholly given to idolatry.
18 Then certain philosophers of the Epicureans, and of the Stoicks, encountered him. And some said, What will this babbler say? other some, He seemeth to be a setter forth of strange gods: because he preached unto them Jesus, and the resurrection.
19 And they took him, and brought him unto Areopagus, saying, May we know what this new doctrine, whereof thou speakest, is?
22 Then Paul stood in the midst of Mars’ hill, and said, Ye men of Athens, I perceive that in all things ye are too superstitious.
23 For as I passed by, and beheld your devotions, I found an altar with this inscription, TO THE UNKNOWN GOD. Whom therefore ye ignorantly worship, him declare I unto you.
30 And the times of this ignorance God winked at; but now commandeth all men every where to repent:
31 Because he hath appointed a day, in the which he will judge the world in righteousness by that man whom he hath ordained; whereof he hath given assurance unto all men, in that he hath raised him from the dead.
(Paul had sent the others to go to Silas and Timothy, and was alone in Athens.
When he saw the people’s idolatry, it says he was stirred.
Then when they brought him to that place, he immediately started preaching, beginning with, “ye are too superstitious”.
That probably didn’t win him any favor with all those listening, yet he kept on preaching.
There is no record that Jesus told Paul to go there alone, and preach.
Yet, his spirit was stirred in him, and he preached.)
(What if we decide to begin speaking publicly for Jesus, like witnessing to the person in line behind us at the grocery store?
It's one thing to hand a tract to the person in front of us, just as they're leaving.
But the person behind us is going to still be there for a while.
If, when we hand them a tract, they ask us, "What is this?" - does that not seem like the door may be opened some?
So, what if we then take the next step, and say that the tract tells how to have a wonderful eternal life with the Savior, and yet how to avoid the eternal fires of hell?
Then, what if they are still listening, perhaps while looking at the tract, we quote some scriptures about the blood of Jesus, and believing on Jesus for everlasting life?
Then, if they are still listening, what if we ask them directly, if they know how to have eternal life, and to avoid eternal damnation?
By what they say, we may, by the help of the Holy Ghost, determine if they are saved already, or not.
If they might not be saved, what if we then ask them if they would like to be saved by Jesus?
If they then say yes, we then have a wide open door, to give them the gospel, and if they are willing, to lead them to Jesus.)
(Why not attempt something for Jesus?)
