Learn how to bring sinners to Jesus Christ the same way Paul did and also, the same way Jesus did.
Dont listen to your church that preach "Come to Christ and he will fill your heart with joy, happieness and love!" this is not biblical and was never used once to convert the sinner.
“If you are a Christian, you are not a citizen of this world trying to get to heaven; you are a citizen of heaven making your way through this world.” - Vance Havner
