What does it mean to make every effort to enter through the narrow door?

Making every effort entails a personal, inward struggle to lay aside self-righteousness and trust fully in Christ. It means recognizing the natural tendency to rely on our works and the need to turn away from them. The effort is about submitting to God's way of salvation—admitting that we cannot arrive at perfection on our own and believe in Christ's finished work. This is a challenging venture against our flesh and is essential for experiencing true salvation and entering into eternal life.
