When Luke tells of the beginning of Jesus public ministry, he briefly mentions the initial positive reception that Jesus experienced.
"And Jesus returned to Galilee in the power of the Spirit, and news about Him spread through all the surrounding district. And He began teaching in their synagogues and was praised by all (Luke 4:14-15)."
What is interesting is that Luke doesn't spend any time detailing those initial success stories. He could have spent a lot of time chronicling the teaching and ministry of Christ for that initial period. However, instead of this, the first detailed story he recounts is about the violent reaction to Christ in Nazareth.
This foreshadows both what will happen to Christ, and what later happens to the church in volume 2, the Book of Acts. It also foreshadows what has happened and will continue to happen to faithful disciples of Christ through the ages. We should not get discouraged when we are rejected and even reviled. Peter says,
"Beloved, do not be surprised at the fiery ordeal among you, which comes upon you for your testing, as though some strange thing were happening to you, but to the degree that you share the sufferings of Christ, keep on rejoicing, so that also at the revelation of His glory you may rejoice with exultation. (1 Pet 4:12-13);"
Being rejected is nothing new or strange. Instead of being fearful or discouraged, we should keep on sharing the Gospel as Jesus continued to do.
