Mystery to save ourselves
Acts 1:1, 3, 8 In my former book, Theophilus, I wrote about all that Jesus began to do and to teach. (1) After his suffering, he showed himself to these men and gave many convincing proofs that he was alive. He appeared to them over a period of forty days and spoke about the kingdom of God. (3) But you will receive power when the Holy Spirit comes on you; and you will be my witnesses in Jerusalem, and in all Judea and Samaria, and to the ends of the earth. (8)
