29 Then the Spirit said to Philip, "Go near and overtake this chariot." 30 So Philip ran to him, and heard him reading the prophet Isaiah, and said, "Do you understand what you are reading?" 31 And he said, "How can I, unless someone guides me?" And he asked Philip to come up and sit with him. 32 The place in the Scripture which he read was this: "He was led as a sheep to the slaughter; And as a lamb before its shearer is silent, So He opened not His mouth. 33 In His humiliation His justice was taken away, And who will declare His generation? For His life is taken from the earth." 34 So the eunuch answered Philip and said, "I ask you, of whom does the prophet say this, of himself or of some other man?" 35 Then Philip opened his mouth, and beginning at this Scripture, preached Jesus to him. 36 Now as they went down the road, they came to some water. And the eunuch said, "See, here is water. What hinders me from being baptized?" 37 Then Philip said, "If you believe with all your heart, you may." And he answered and said, "I believe that Jesus Christ is the Son of God." 38 So he commanded the chariot to stand still. And both Philip and the eunuch went down into the water, and he baptized him. 39 Now when they came up out of the water, the Spirit of the Lord caught Philip away, so that the eunuch saw him no more; and he went on his way rejoicing. 40 But Philip was found at Azotus. And passing through, he preached in all the cities till he came to Caesarea.

Philip was directed to go to a desert. Sometimes God opens a door of opportunity to his ministers in very unlikely places. We should study to do good to those we come into company with by travelling. We should not be so shy of all strangers as some affect to be. As to those of whom we know nothing else, we know this, that they have souls. It is wisdom for men of business to redeem time for holy duties; to fill up every minute with something which will turn to a good account. In reading the word of God, we should often pause, to inquire of whom and of what the sacred writers spake; but especially our thoughts should be employed about the Redeemer. The Ethiopian was convinced by the teaching of the Holy Spirit, of the exact fulfilment of the Scripture, was made to understand the nature of the Messiah's kingdom and salvation, and desired to be numbered among the disciples of Christ. Those who seek the truth, and employ their time in searching the Scriptures, will be sure to reap advantages. The avowal of the Ethiopian must be understood as expressing simple reliance on Christ for salvation, and unreserved devotion to Him. Let us not be satisfied till we get faith, as the Ethiopian did, by diligent study of the Holy Scriptures, and the teaching of the Spirit of God; let us not be satisfied till we get it fixed as a principle in our hearts. As soon as he was baptized, the Spirit of God took Philip from him, so that he saw him no more; but this tended to confirm his faith. When the inquirer after salvation becomes acquainted with Jesus and his gospel, he will go on his way rejoicing, and will fill up his station in society, and discharge his duties, from other motives, and in another manner than heretofore. Though baptized in the name of the Father, Son, and Holy Ghost, with water, it is not enough without the baptism of the Holy Ghost. Lord, grant this to every one of us; then shall we go on our way rejoicing.
