1 Corinthians 15:1 Now, brothers and sisters, I want to remind you of the gospel I preached to you, which you received and on which you have taken your stand.
When we tell someone about Christ, show them the Gospel or demonstrate to them how we live as Christians, it should not be a once off occurrence!
How is anyone going to see how much Christ actually means to us if we are going to only show them a snippet of what they can gain through living with Christ themselves.
The apostles went out continually and preached the Gospel to others; something we should be doing as well.
