The parable of the sower (Matthew 13:3-8;18-23) is an excellent example of the power of multiplication. Here we find that that the seed of God’s word is sown in four types of hearts. The first three types of hearts do not produce fruit:Those who do not believe, those who do not become rooted and grounded in the word, and those who are not steadfastly devoted in love with God but are distracted by the cares of this world.

The key to bearing fruit is the proper spiritual formation. Things like understanding and claiming God’s promises through confession (Matt 12:33-35; Rom 10:8-10; 2 Peter2:2) will strengthen our faith. Prayer and worship, both personal and public will strengthen our relationship with God. Bible study allows our minds to be rooted and grounded in Scriptural principles. When we do these things, the Word that is planted in our hearts will produce much fruit.

The nature of the production of fruit is that of multiplication. We are told that the good heart produces 30, 60 and 100 times. This has implications manifold for individual success and for reproducing our selves through evangelism.

The charter below should illustrate the power of the principle of multiplication. Let’s say that you start a group with just a few people and you set a goal to reach at least 2-4 people a year per member. Let’s say that we keep 25-50 percent of these. Doubling a year would yield this. The following table assumes a 100% growth (2x) a year. I believe this is a conservative estimate

#Starting members:	2	4	8	16	32	8 (5x )
1st  year	4	8	16	32	64	40
2nd  year	8	16	32	64	128	200
3rd  year	16	32	64	128	256	1,000
4th  year	32	64	128	256	512	5,000
5th  year	64	128	256	512	1,024	25,000
6th  year	128	256	512	1,024	2,048	125,000
7th  year	256	512	1,024	2,048	4,096	625,000
8th  year	512	1,024	2,048	4,096	8,192	3,125,000

The key to maintaining this is to have people committed to this vision and to constantly train people in proper spiritual formation. This is how the New Testament Church multiplied. They multiplied from  120 people in AD 30 to 1 million people at AD 100 (http://answers.google.com/answers/threadview?id=320929)

This averages to a  average annual  multiplication of about  5x (400% growth a year!!!!) rather than merely doubling. The key to keeping people committed to this vision is the right spiritual formation in people.
