Witnessing is personal evangelism by believers to unsaved mankind – the communication of the Gospel of Christ on the cross to the lost. The believer has a responsibility to be accurate in presenting the Gospel message. Then, the one who hears is responsible to respond or reject. Their choice (volition) determines their eternal destiny. Witnessing is serious because eternity with or without God is at stake. Know the One in whom you have believed. Know your Gospel. Know how to defend and speak about your faith.
