The path is narrow, but Jesus never said it was straight. I’ve heard people talk about “staying on the straight and narrow” but this is what I read:
“For the gate is narrow and the way is hard that leads to life, and those who find it are few.”
Matthew 7:14, ESV
The path that you follow God on isn’t promised to be a straight one; in fact, it is full of twists and turns, hills mounting up before you and winding descents into valleys below. It is narrow, purposed, very precise, no room for meandering and wondering about as there would be on a wider road. You are meant to go somewhere specific, and I don’t mean heaven. Ultimately when following Christ you are promised to get there. But there’s a place you’re assigned to be, while you’re living and breathing on the earth; you bring heaven with you and within you everywhere you go. The path isn’t hard for the sake of salvation, because Jesus took care of that on the cross. It’s because following Him requires everything, at all times, and we don’t want to give it. Where you go on the path as a follower of Jesus Christ is where the kingdom of God is coming. What you leave behind you is a straight path.
As it is written in the book of the words of Isaiah the prophet, “The voice of one crying in the wilderness: ‘Prepare the way of the Lord, make His paths straight.’”
Luke 3:4, ESV
When you are following Christ, consumed by the fire of His Spirit, on the path He has laid before you, what you leave in your wake is a path made straight and leading directly to the Lord, which everyone who comes after you will follow straight into His arms. His presence and glory is the goal, and bringing His children to Him is the honor, of forging ahead on this winding, narrow path.
