My main Christian calling is discipleship. But, like all Christians, I'm also called to evangelize.
It's good to try evangelism methods outside our comfort zone. It's part of growth. But, in the end, our unique gifts and personality should determine our methods of evangelism.
Forcing ourselves or others into a mold produces guilt, and guilt isn't an effective motivation for evangelism.
For example, I've tried street evangelism, walking up to perfect strangers and sharing Christ. Some people find this the most natural way to share Christ, and it was good for me to give it a try. But it's not my "niche."
God may ask me to do it on rare occasions, but for the most part He uses me as He's gifted me.
If you've been guilted by another person's evangelism script or formula, relax.
The best way to share Christ is to be sensitive to God's Spirit and develop your own style of evangelism (Ephesians 2:10). Take time today to consider ways you might do that more deliberately.
