Summary: Your intellect and your five senses are hollering “No! It won’t work. I’ll make a fool of myself.” But God’s Word and His Spirit say “Yes!” We are faced daily with challenges to walk by faith, not by sight.
•• Philip took the proverbial “long walk on a short pier”. He had been having an immensely successful revival in the city of Samaria, with many conversions and healings, signs, and wonders manifested (Acts 8:5-8). Philip immediately left all that to follow the instructions from “an angel of the Lord” to go down to the desert (Acts 8:26-27), where he was to encounter the Ethiopian official.
•• Just imagine the scene, with uninvited Philip running up to the chariot of the queen’s treasurer, then jogging alongside! Talk about walking by faith! ... or more precisely in this case, running by faith! One of the Ethiopian treasurer’s guards could easily have run Philip through with a spear.
•• But the Spirit of God (8:29) was the instigator of Philip’s “long walk on a short pier”, and the Ethiopian high official was wonderfully ministered to by Philip, was saved and baptized in water, and went on his way rejoicing in his newfound salvation (8:36-39).
•• Philip’s obedience to the Lord’s prompting is a classic biblical illustration of God’s desire that we “walk by faith, not by sight” (2 Corinthians 5:7, KJV). Philip did not “see” the results in advance. No, but rather he stepped forth in faith, in obedience to what he perceived as God’s leading.
•• When it comes to witnessing, let us take some long walks on some short piers.
• What do we have to lose? What’s the worst that might happen? — we get rejected ... we get made fun of ... we get ignored...
• What’s the best that might happen? — The person with whom we share the Gospel gets saved and spends eternity in heaven!
•• Many years ago my wife took that “long walk” of faith with a good friend of hers. She risked that friendship by making a strong presentation of the Lord’s salvation to her friend, caring more for her eternal soul than for the friendship that she was risking by her bold witness. Thankfully, the lady accepted my wife’s testimony, got saved, and has served God now for several decades, including time with her husband on the mission field.
•• Today your mission field is all around you. Each morning ask the Lord to allow you to touch someone’s life for Jesus Christ. Then listen for the Holy Spirit’s promptings inclining you to speak to this or that person. Then do it — take the walk of faith, step forth on that Holy Ghost leading. Walk by faith, not by sight or mental calculations.
Acts 9:32-35 As Peter traveled about the country, he went to visit the saints in Lydda.  There he found a man named Aeneas, a paralytic who had been bedridden for eight years.  “Aeneas,” Peter said to him, “Jesus christ heals you. Get up and take care of your mat.” Immediately Aeneas got up.  All those who lived in Lydda and Sharon saw him and turned to the Lord.
•• Healing is an area where we have numerous opportunities to walk by faith, not by sight. Just go ahead!
• Believe Jesus when He said that you “shall lay hands on the sick and they shall recover” (Mark 16:18, KJV).
• Believe God when He said, “I am the Lord who heals you” (Exodus 15:26).
