Matthew 7:13-14, Jesus is not teaching that sinners save themselves by dropping enough baggage at the door, the gospel is not moral fitness squeezed through a small entrance. Salvation is God’s grace received by faith, because of what Christ has done, not wages earned by religious effort. But the grace that receives sinners does not make peace with rebellion. The Christ who forgives also calls. The savior who also welcomes commands. The spirit who comforts also sanctifies. In language Christians across traditions can recognize, genuine faith bears fruit, the narrow gate does not mean God is reluctant to save, it means the entrance to life is not wide enough for a divided allegiance.
Now the traveler gets through the gate and expects open ground, but Jesus says something more, Matthew 7:14, difficult is the way which leads to life. The Greek word for “way” is hodos, a road or path, but the word translated “difficult” is the one that surprises people. Matthew uses a form connected to the Greek verb tethlimmene, which means to press, squeeze, crowd, afflict or constrict, the road is not merely unpopular, it is pressed in. The picture changes, this is no longer only a tight doorway, it is a road that keeps narrowing around the traveler. Consider a path cut between rock walls after the sun has dropped low, the entrance is behind you now, but the road has not become spacious.
