Radical Evangelism In God's Name
Preach
Preach the word of God. Be prepared, whether the time is favorable or not. Patiently correct, rebuke, and encourage your people with good teaching. For a time is coming when people will no longer listen to sound and wholesome teaching. They will follow their own desires and will look for teachers who will tell them whatever their itching ears want to hear. They will reject the truth and chase after myths. But you should keep a clear mind in every situation. Don’t be afraid of suffering for the Lord. Work at telling others the Good News, and fully carry out the ministry God has given you. (2 Timothy 4:2-5 NLT)​
As followers of God (Christians) our calling is to "Preach".

And then he told them, "Go into all the world and preach the Good News to everyone. (Mark 16:15 NLT)
Go you therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Spirit: (Matthew 28:19 NKJV)
It doesn't get any simpler than that! I am not going to touch up on this, as it is 101% self explanitory! Now just do it, like the word of God says! :)
