But He said to them: It is not for you to know the times or the moments which the Father hath put in His own power: but you shall receive the power of the Holy Ghost coming upon you, and you shall be witnesses unto Me in Jerusalem, and in all Judea and Samaria, and even to the uttermost part of the earth. (Acts 1:7-8)
