Luke 14:25  (NKJV)
²⁵ Now great multitudes went with Him. And He turned and said to them,  source

This verse is speaking of Yeshua, of course.

After Jesus’ resurrection, ascension, and Holy Spirit had come the Disciples preached.

Acts 2:41 (AMP) 
⁴¹ So then, those who accepted his message were baptized; and on that day about 3,000 souls were added [to the body of believers]. source

Acts 2:46-47 (NKJV) 
⁴⁶ So continuing daily with one accord in the temple, and breaking bread from house to house, they ate their food with gladness and simplicity of heart, ⁴⁷ praising God and having favor with all the people. And the Lord added to the church daily those who were being saved. source

Acts 4:4  (AMP) ⁴ But many of those who heard the message [of salvation] believed [in Jesus and accepted Him as the Christ]. And the number of the men came to be about 5,000.  source

Spring forward from Century 1 to now the 21st Century – what happened? 
Multitudes followed Yeshua to hear what He would say.
Thousands upon thousands, even 3,000 in a day heard Peter preach and believed The Gospel. They got SAVED.

Where are the multitudes in the 21st Century being CHANGED by The GOSPEL of JESUS CHRIST? 
What happened? 

Will you pray?
Will you pray according to Luke 10:2?

Luke 10:2  (AMP)
