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.
“I have but one candle of life to burn, and I would rather burn it out in a land filled with darkness than in a land flooded with light.” - John Keith Falconer
