This is a common question. If making disciples is the what we are to be about, how do we know if we are accomplishing this effectively? The difference between converts and disciples is that disciples obey what Christ commanded. Converts listen and might believe what they are taught, but little is applied in their own lives.
With converts, activity takes the place of obedience. We are easily seduced into thinking if we are involved in Christian activities, we are doing the right thing. Being obedient disciples is something quite different. It is not activity oriented. It is obedience to Christ's commands. Not how much we know of the Bible, but how much we obey what Christ says.
Everyone knows, or at least has heard about the Ten Commandments in the Old Testament. But how many Christians know and can quote the Ten Commandments of Christ?
As part of the Great Commission Jesus clearly instructs "teaching them to observe ALL that I commanded you..." What exactly did Christ command?
One quick test to see how much of a disciple we really are is to grade ourselves on a scale of 1-10 on the approximate degree of obedience to each of the following commandments.
Add up the points. If you score 50% or greater, you lean towards being a disciple. If 50% or less, you lean more towards being a convert.
1) LOVE THE LORD YOUR GOD WITH ALL YOUR HEART, AND WITH ALL YOUR SOUL, AND WITH ALL YOUR MIND, AND WITH ALL YOUR STRENGTH...YOU SHALL LOVE YOUR NEIGHBOR AS YOURSELF. The Great Commandment: Matthew 22:37-40, Mark 12:28-31.
2) Go therefore and make disciples of all the nations, baptizing them in the name of the Father and the Son and the Holy Spirit, teaching them to observe all that I commanded you. The Great Commission: Matthew 28:19-20.
3) ...love one another. The New Commandment: John 13:34-35, 15:12.
4) ...seek first His kingdom and His righteousness... The Priority commandment for every believer: Matthew 6:33.
5) ...do this in remembrance of Me... The Lord's Supper: Luke 20:14-20, 1 Corinthians 12:23-26.
6) ...wash one another's feet...you also should do as I did to you... The Great Example Commandment: John 13:14-15.
7) Abide in Me... The Commandment that is the secret to a fruitful life: John 15:4-8.
8) ...beseech the Lord of the harvest to send out laborers into His harvest... The only specific request Christ commanded his disciples to pray besides the Lord's Prayer: Luke 10:2, Matthew 9:38.
9) ...do not pass judgment...do not condemn...pardon...give... General Commandments of Jesus for victorious living: Luke 6:37-38.
10) ...love your enemies...do good to those who hate you...bless those who curse you...pray for those who mistreat you... Commandments for loving our enemies: Luke 6:27-36, Matthew 5:43-48.
Christians should not measure their spiritual maturity based upon their knowledge of the Gospel, but upon their obedience of what they know of the Gospel. We should never confuse our knowing the commands of Christ with obeying them in our personal lives. The Christian walk is not about what we know, but about how much we OBEY what it is we know.
