It starts with life, energy, fire, and warmth that reaches out naturally. We call that love. Love is not an effort, though it may cause us great effort. Life, light, and love shine outward. They illuminate and cause things to become clear.
Biblical evangelism begins with being.
We cannot generate what we have not received from God. When we receive life and light, we have it to give. It is what we are that gives credibility to what we say. Out of what we are comes what we do. So, being causes doing.
