God is the mater in my life and the master of missionary

Acts 8:26-34
An angel of the Lord said to Philip, "Go south to the road - the desert road - that goes down from Jerusalem to Gaza." So he started out, and on his way he met an Ethiopian eunuch, an important official in charge of all the treasury of Candace, queen of the Ethiopians.
Do you understand what you are reading? Book of Isaiah the prophet.
At the height of Philip's flourishing Samaritan campaign God calls him away to meet the need of an individual. Eunuchs were barred(禁止) from the Temple, but God know this foreigner is read to receive the Good News about Jesus.
An Ethiopian: The man, a Jewish convert, was treasurer of the old kingdom of Cush, in northern Sudan.
Candace: The title of the queen mother who ruled the country on behalf of her son. The king himself, defiled as the child of the sun-god, was considered too holy for such secular(世俗) functions.
Scripture: Isaiah 53:7-8 The quotation is from the Greek text which differs slightly from the Hebrew text on which out Old Testament is based.
Why?
Philip is obey the guiding of the Holy Spirit and angel. Even he was preaching Jesus in Samaritan well. God knows which mission is more important.
God led Philip to the desert, it might let us do not why? But God has his way and his work, Philip is join the work of God.
God is the master in all those good news preaching.
How?
Our life is same as above story, God is my master in my life, I need to subdue to the Lord, who knows my way and work with the Lord will be he best. I accepted to attend the gospel team of Japan on November. I believe that if is the way of the Lord, God will handle all of schedule for me.
