Time:
Discipleship is a process, it takes time. It is not meant to be transformation quickly. (2 years, 40 days, 12 weeks, etc)
Our Spiritual formation and relationship with God is on-going and matures slowly. We are to be investing our lives into learning more about God.
Churches that are becoming more effective in discipleship have 2 or 3 year processes of learning the general worldview of Christianity, they also encourage and hold other classes for more mature Christians who want more training...(which all this is fine and great)
On one hand, it is difficult to but all of the Christian worldview in a 2 or 3 year program.
On the other hand, American Christians today need some sort of structure:
because we (as Christians) are losing out in discipleship and in spiritual formation and our Christian worldview. Americans have prioritized everything else in conquering their American dreams and have lost their worldview. They have lost their faith to secular world.
So I am encouraging these two-year processes but I am also saying that is not the end! Do not stop when the program is over because our faith is a process. It is a relationship of maturity. We continue learning more and more about God and being transformed more and more every day.
But even these "weak" and shallow structured programs are not enough. Because Christians will not make time for them The problem is no the program, this is a starting block.
The problem is in priorities. Christians say they have a time problem, but I beg to differ. They have a love problem and are not making time for their first love. :(
