Andrew Murray emphasizes the twofold conflict of the Christian life, beginning with the immediate need for the unconverted to strive to enter through the narrow door of salvation. Once inside, believers face a lifelong battle characterized by faith, as they contend against spiritual enemies. Murray clarifies that true conflict arises not from struggling against God, but from the ongoing fight of faith, where believers must remain in Christ, their stronghold, to overcome. He highlights that victory comes through faith in Jesus, who empowers believers to stand firm against the enemy. Ultimately, the sermon calls Christians to understand their position in Christ and to rely on His strength for the battles they face.
