Missional is the perspective to see people as God does and to engage in the activity of reaching them. The church on mission is the church as God intended. (Missional Manifesto)
I really love this definition of what it means to be "Missional". It's simple and understandable and presents a deep challenge.
"To see people as God does" - without the hindrance of my previous experiences, judgmental nature, self-centered heart. To really love. To really see. To be able to encounter each person as God's beloved child; to look into their eyes and heart and to risk caring boldly.
"To engage in the activity of reaching..." - this means setting forth with purpose, taking action beyond my bubble of home and friends and church.
Our church tag line is "A safe place to grow in faith" and while we need that haven for restoration and building our own deep reserves, we must not forget to move outward into a world that is real and hurting. As disciples we are called to make those same "safe places" wherever we go. Our goal should be to become "Safe People" to others.
Lastly it's easy to wait for the Missional program or ministry ...and to miss the opportunity to embrace a Missional mindset, where our walking and talking is our ministry. Where we freely share the great gift of our relationship with God. "The Church on mission" is you and me folks. Today and every day. Living out the gospel.
