“There is no obedience that does not have its eyes on either God or neighbor. An obedience that is motivated by what we will get out of it is no obedience at all.”
The idea is that Jesus has called His church to make disciples, and since the church doesn’t look much like the One they are following, the people need to be changed.
In the twinkling of that eye the perishable will become imperishable, and our bodies will be changed and become more glorious than we ever could have imagined.
