God does not ask us to seek converts, He simply asks us to do Discipleship. Discipleship is modeling and teaching Christians the precepts of the Bible-mainly prayer, doctrine, Christian living, and worship. Yes, we are still to evangelize, but that is not our main mission and call! When we evangelize, we must realize that it is the role of the Holy Spirit to bring people into an intimate relationship with God. This is an act of divine intervention and grace.
What are we to do first in all situations? Is it to complain? Argue with one another? Be stressed? NO! We are called to pray...
Grace basically means an undeserved act of kindness. This is one of the most enduring actions of love that could ever be conceived.
The Gospel simply put is "The Good News" of what Christ has done for you and me. This is the message and meaning of who and what Jesus is and has done.
