"Apologetics" is the "ready defense" that we need to be prepared to give anyone "who asks you to give an account for the hope that is in you" with "gentleness and respect." (1 Peter 3:15). In the past 100 years, this has taken the form of using Reason and Philosophy and Argument to try to help people with Modern/Enlightenment sensibilities to get past their mental stumbling blocks on their way to meeting Jesus Christ.
I think, since we are entering a postmodern age, that such techniques need to be replaced with a more "embodied apologetic" displayed in the way we live and love and worship.
“Theology” is our “in-house debates/discussions” about things we are trying to understand in the Bible (things like the nature of God, the end-times, Calvinism v. Arminianism, the meaning of the Atonement). These are not concerns of those outside the faith--they are concerns of those already in. It is a noble pursuit to seek to more purely understand God (which is what "theology" is supposed to be!).
So, here is what needs to change:
Our apologetics needs to change--from a purely reasoned argument (though we cannot ditch Reason and become unthinking) toward an embodied (incarnational) apologetic. We still need to know how to answer people’s questions, but before that, we need to show them that God is real and that living in Christ’s Kingdom is a superior life that is attractive to the outsider.
Our theology needs to change as well--from a purely academic exercise (though we must always love God with our “minds”) toward an embodied (incarnational) theology that takes those intellectual concepts and immediately applies them to the way we live in the Kingdom of God. Theology needs to be moved down from the ivory tower and put on the streets. Theology needs to be figured out not in isolation by individual scholars but in community.
