Hello, I am doing a Bible study about gifts received from the Holy Spirit. I have a small problem: I cannot understand the difference between „to evangelize” (from the Greek verb *euangelizo) and „*to proclaim*” (from the *Greek verb *kerusso). *For me both are the same, but the author insist for the readers to know the different meaning that the terms have.If somebody can help me, it would be awesome. 🙂 I hope I made myself understood.
