Criers of the Word of God
"And he said unto them, Go ye into all the world, and preach the gospel to every creature." Mark 16:15
I think we can all preach the word of the Lord and give examples of the good deeds that he wants us to do, but I also think we should study the Bible and prepare well, because the simple fact of wanting to be an evangelist, I think the temptations and sins would haunt us with the aim of moving us away from the path of truth and life, Jesus was tempted by the son of the father, we too can be tempted and not only that, sin.
Entnces that we must do if we want to talk to other people about the bible and the truth and eternal life, take our main weapon and study it, read, learn, so once we already cults in the word, we can serve God and water the darkness with the light of hope that is the word of God
"You are world's light; a city set on a hill can not be hidden. Neither does a light come on and it is placed under a bushel, but on the candlestick, and it gives light to all who are in the house. Let your light so shine before men, that they may see your good works, and glorify your Father who is in heaven. "Matthew 5: 14-16
