People look for answers. Something you can read off of a piece of paper & pass around. Jesus didn't come as God's answer man, writing book after book of pro-God arguments. He came as the Son of God wanting to help people meet His incredible Father.
Jesus invited us to embrace His Father. He didn't come to satisfy our intellectual checklists to make His way make the most sense as the best bet of all world views.
So many wrestle with the questions of "God why do these bad things happen?" or "Where were you during these tragedies?"
Answers cannot replace a Father's love & comfort. Truth is made to speak to the heart first. We need to look for our Father here & now. People don't find God when looking for answers or certainty or even when they say, "God where are you?" God is found, right here, when His children cry for their Daddy.
Sadly Christianity has been made out to be primarily an academic pursuit centered around a book that teaches us how to ACT right rather than a family centered around its loving Father who teaches us how to LOVE one another by experiencing our Father's love for us.
Our Father is not a God who is also a Father but a Father who is also God. Jesus came not to show us a God to serve but to show us our Father as a friend.
The problem with most evangelism is that we seek to tell people ABOUT GOD instead of inviting people, as Jesus did, to KNOW OUR FATHER.
