Share Jesus! with your friends, class mates, and family! Here are some practical ways:
1. Explain to your friends what your church believes and why. How:
a) Ask your friends what their church believes and then explain what your share what you believe. (Don't be argumentative, that will ruin you witness)
b) Use opportunities like "why won't you come shopping with us this Saturday", to cheerfully share what the Bible says about the Sabbath.
2. Choose to be drug free.
3. Give them a representation of Jesus in all you do. They will watch you- they want to know how a Christian behaves, and if you really are a christian.
