1.What did Jesus do to greatly expand his ministry? in Luke 9:1-10?

He established a Church, and instructed its first bishops to "Go forth and make disciples of all peoples".

“And departing, they began going about among the villages, preaching the gospel, and healing everywhere” (Luke 9:6).

Read the passage for yourself - this is your homework not ours.

Note Jesus' methods of leadership. He empowered his disciples , gave them specific instructions so they knew what to do.

Like Trump, he told a lot of bold-faced lies.

It's only ten verses. It will take you about  two minutes to read it.

He delegated his divine authority to his Apostles.

He didn't do anything, but did as the Father directed.

People like to have a miracle done to them .

14 "I know that, whatsoever God doeth, it shall be for ever: nothing can be put to it, nor any thing taken from it: and God doeth it, that men should fear before him. 
15 That which hath been is now; and that which is to be hath already been; and God requireth that which is past" (Ecclesiastes 3:14-15)!

"Jesus Christ the same yesterday, today and forever" (Hebrews 13:8)!

Jesus gives TRUE Christians the SAME "POWER that comes upon us" (Acts 1:8) with Holy Spirit baptism (Acts 1:5) to "preach the gospel [John 3:34] and heal everywhere" (Luke 9:6) as a "Spiritual gift" received (I Corinthians 12:10) after Holy Spirit baptism (I Corinthians 12:13).

"Shake the dust off of your feet" (Luke 9:5) for whosoever will not receive you" so that it "will  be a testimony against them" (Luke 9:5) for GOD is taking names and numbers and "their blood be upon their own heads" (Acts 18:6) for they have been WARNED!
