1 Thessalonians 2:3-4
3 For the appeal we make does not flow from error or from impure motives, neither do we try to trick people. 4 Instead, since God has tested us and found us fit to be entrusted with Good News, this is how we speak: not to win favor with people but with God, who tests our hearts.
Witnessing to others is not about saving souls, even though that can be a result. It is about obeying and pleasing God. Adonai Tza’vaot, the Lord of Host commands us to share His Word, it is the Ruach HaKodesh, the Holy Spirit that convicts. How can we as believers keep silent if we truely want to please God?
