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. Converts are easily seduced into thinking if they are involved in Christian activities, they are doing the right things, and that is what makes them a follower of Christ.
Being a disciple of Jesus Christ 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 said to do.
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. The Great Commandment: Matthew 22:37-40
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...
2) You shall love your neighbor as yourself... The Great Commandment: Mark 12:28-31.
3) 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.
4) Love one another. The New Commandment: John 13:34-35, 15:12.
5) Seek first His kingdom and His righteousness. The Priority commandment for every believer: Matthew 6:33.
6) Do this in remembrance of Me. The Lord's Supper: Luke 20:14-20, 1 Corinthians 12:23-26, gathering in remembrance of Him
7) Wash one another's feet...you also should do as I did to you. The Great Example Commandment: John 13:14-15.
8) Abide in Me. The Commandment that is the secret to a fruitful life: John 15:4-8.
9) 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.)
10) Love your enemies...Do good to those who hate you...Bless those who curse you...Pray for those who mistreat you... Do not pass judgment...Do not condemn...Pardon...Give... General Commandments of Jesus for victorious living: Luke 6:27-38, Matthew 5:43-48.
Christians should not measure their standing with the Lord (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.
