What is the narrow gate that leads to life?

In Matthew 7:13, the narrow gate is the way of grace, and the wide or broad gate is the way of self-righteousness. Not many find the narrow gate (Matthew 7:14), because the religions of the world encourage good behavior for salvation, and this is very appealing to people. Scripture is clear: We must set aside our efforts to earn or maintain righteousness with God and humble ourselves by receiving grace (James 4:6).
