We saw last time, in Mystery 1 Solved, the same day Jesus rose from the dead, he gave his disciples the Holy Ghost/Spirit, all but Thomas. Thomas was not present at that time. We saw how Jesus gave them the Holy Spirit was the same way God gave Adam life, he breathed on them.
John 20:22-24 KJV “And when he had said this, he breathed on them, and saith unto them, Receive ye the Holy Ghost:
 Whose soever sins ye remit, they are remitted unto them; and whose soever sins ye retain, they are retained.
 But Thomas, one of the twelve, called Didymus, was not with them when Jesus came.”
Later, Thomas shows up. The disciples tell Thomas what happened but Thomas didn’t believe them. Then 8 days later, Jesus shows up again. Now remember, all the disciples but Thomas have the Holy Ghost/Spirit. So Jesus then deals with Thomas and Thomas believes.
Then John 21 deals with proofs of Jesus resurrection and Jesus talking with his disciples.
Question 2: If the disciples received the Holy Spirit on the same day as the resurrection, look at Luke 10:17-20.
“And the seventy returned again with joy, saying, Lord, even the devils are subject unto us through thy name.
 And he said unto them, I beheld Satan as lightning fall from heaven.
 Behold, I give unto you power to tread on serpents and scorpions, and over all the power of the enemy: and nothing shall by any means hurt you.
 Notwithstanding in this rejoice not, that the spirits are subject unto you; but rather rejoice, because your names are written in heaven.”
How did these 70 believers have power over all power of the enemy when the Holy Spirit was not given yet?
And after that we see Jesus rejoiced “in spirit” meaning his own spirit not the Holy Spirit. So we see that 70 believers (verse 20) were given power, by Jesus, power over “all the power of the enemy”. So was Jesus referring to the 70 only? Or to all believers? We will pick it up from here next time.
God loves you. Jesus Christ died on the cross to pay our sin debt. Receive him as your Lord and Saviour.
