When we see Jesus calling the twelve it is not a one-time calling, but a first call to a lifetime call to follow Him. And in that moment, when Jesus called this rag-tag group, he has called them to be disciples; followers. Of course they would become more than disciples, they would also become apostles (sent ones). When we were called by God to follow Him we were called to much more than just to believe and acknowledge. We were called to get up and follow Him. And it wasn't a one-time call, but it was a first call for our lifetime call.
Are we being disciples?
How do we stay in a continued calling with Jesus?
He has called and our response is to follow whole-heartedly with all of our soul, mind, strength through love for Him and our neighbor.
