We must take every appropriate opportunity to bear humble but joyful testimony to what the Lord has done for us and offers to all. And we must be ready to explain the way to faith and welcome those who want to take it. This is entirely different from proselytism. Proselytism seeks to enforce. Evangelism seeks to woo.
Proselytism relies on force.
Evangelism relies on love. Proselytism is bad news. Evangelism is Good News. Proselytism applies the whip. Evangelism holds forth the carrot.
