Scripture to Memorize: Acts 1:8
8 But you will receive power when the Holy Spirit has come upon you, and you will be my witnesses in Jerusalem and in all Judea and Samaria, and to the end of the earth.”
Day 1--Read: Acts 1:4-8
4 And while staying with them he ordered them not to depart from Jerusalem, but to wait for the promise of the Father, which, he said, “you heard from me; 5 for John baptized with water, but you will be baptized with the Holy Spirit not many days from now.”
6 So when they had come together, they asked him, “Lord, will you at this time restore the kingdom to Israel?” 7 He said to them, “It is not for you to know times or seasons that the Father has fixed by his own authority. 8 But you will receive power when the Holy Spirit has come upon you, and you will be my witnesses in Jerusalem and in all Judea and Samaria, and to the end of the earth.”
Reflect: What did Jesus promise his followers? What were they hoping for? How did he respond to their request?
Consider: Indeed John had predicted a Spirit baptism by the Lord Jesus. The greatness of Christ was seen in the fact that John identified people with himself by water baptism; Christ Jesus would join His followers to Himself by the Holy Spirit. The word baptized, which normally means “dipped or immersed,” here has the idea of “uniting with” (cf. 1 Cor. 10:1–2). The Lord made the same prediction of Spirit baptism that John made (Matt. 3:11; Mark 1:8; cf. Acts 11:16).
Respond: Why was the coming of the Holy Spirit essential to the disciples’ obeying Jesus’ Great Commission? How would the Spirit empower the disciples to carry out Jesus’ mission? How does this help us understand the role of the Spirit in our lives today? Why is He important for the ongoing mission of the church?
