A witness is one who testifies to the certainty of an event. As such, the apostles gave witness to the resurrection of the Lord Jesus Christ. By doing so, they were declaring the resurrection to be an absolute truth. The disciples physically witnessed the fact that the Lord Jesus Christ had been put to death, but was alive and well. Although no believer today physically saw the birth, life, death, burial, or resurrection of the Lord Jesus Christ, we can and should still testify to its truthfulness. In order to offer an adequate witness of the Lord’s saving grace, an individual must first have experienced the new birth combined with the witness of God’s indwelling Spirit (1 John 5:10).
Christians should first and foremost focus on their walk with the Lord. As such, believers are instructed to add virtue, knowledge, temperance, patience, godliness, brotherly kindness, and charity to their faith. However, notice that every believer is to be “giving all diligence” (with great effort, but without haste). Of all these graces mentioned, faith seems to be the most foundational of them all. Unfortunately, far too many believers never grow beyond faith, making them unable to put forth much diligence in adding the other graces. Believers should be growing in grace daily (like those listed above) and in the knowledge of our Lord and Saviour (2 Peter 3:18). The word of God remains the only viable source from whence this diligent growth springs forth (1 Peter 2:2).
