"Instead, they had some points of dispute with him about their own religion and about a dead man named Jesus who Paul claimed was alive. I was at a loss how to investigate such matters; so I asked if he would be willing to go to Jerusalem and stand trial there on these charges." - Acts 25:19-20
I've been using a computer on a daily basis for over eighteen years. As time has passed, I have become reasonably skilled in using this great tool. Occasionally, I am called upon to explain the features of some Bible software to a newbie. The results are often quite frustrating. They don't understand the basics and it takes great patience to show them the way.
This Bible reading provides a similar revelation of the unbeliever's mind toward the Gospel. After all was explained, Festus was at a loss. He understood Paul's claim that Jesus was alive, but he failed to see the significance. In the end, it all seemed to be religious "mumbo jumbo". Festus needed someone who would, with great patience show him the way.
Have you grown weary of that "someone" who just doesn't get it? Have you given the gospel to them time and again and they are still confused? Prayer is imperative, but patience is critical as well. The gospel may seem so simple to you, after knowing the Lord for many years. But the unbeliever needs someone who will take the time and patiently show them the way.
