Why is the concept of strengthening important for Christians?

Strengthening one another is essential within the Christian community to foster spiritual growth and resilience against trials. According to the sermon, the exhortation for Peter to 'strengthen thy brethren' serves as a reminder that Christians are not called to walk alone but are to support each other in faith. This support is especially critical when believers face doubts, struggles, or moments of weakness. By uplifting one another, we fulfill the law of Christ, and together we are reminded of God's abiding presence and strength in our lives. Such mutual encouragement helps to build a strong and united church where all members can grow in grace and knowledge of Jesus Christ.
