The term "straight paths" is often used in the Scripture. For example, in Proverbs 3:5,6, it reads, "Trust in the Lord with all your heart and don't lean on your own understanding. In all your ways acknowledge him and he will make your PATH STRAIGHTS." In today's reading, Mark 1:3, there is the prophecy from Isaiah 40 and Malachi 3 about the forerunner, "my messenger" who must precede Messiah's coming. He will proclaim, "Prepare the way of the Lord, make his PATHS STRAIGHT."
What does this mean? In today's American society, most of our streets are well lit. When we walk at night, we don't much have to worry about tripping and falling. We can see a few feet in front of us. However, in Old and New Testament times, this was not the case. When walking at night, one walked in darkness. One had to worry about tripping, falling and perhaps being severely injured. Therefore, one of the most important paths someone could walk on was a "straight path". A crooked one afforded much danger for a traveler. A straight one afforded much more safety.
God wants the path to Jesus to be a "straight path." He doesn't want it to be difficult or treacherous. It needs to be a path that is easily traveled. That's why it must be a path of GRACE. It cannot involve our human efforts to have a relationship with God. Otherwise, we'll be constantly falling and failing. We can never be righteous enough.
That's the path John helped prepare. It's the one Jesus walks. After all, Jesus himself said, "I am the WAY (the path), the truth and the life." His grace is our only path. It's a straight path. On it you are assured of God's constant, abiding love. It can't ever be taken away. You'll never trip and fall on it.
Enjoy your walk today on Jesus' straight path.
