What is the life of witness?

The life of witness (Acts 1:8) is preaching the gospel of Jesus Christ,

the mission that the Lord has given me, which is far more precious that our lives (20:24),

starting at home, then in the church and outside of the church such as, our works and society,

according to the Holy Spirit’s guidance, by loving our neighbors and have good influences on them

as long as we are with them.
