To be a disciple of Christ is to abide in His word, which is a necessary component of a Christian’s life (John 8:31-32; 15:1-7).
I think that one who does not take up their cross and follow Jesus cannot be His disciple (Luke 9:23; 14:27). And it is a commitment (Luke 14:33; Galatians 5:24; Matthew 10:37-39; 16:24-25).
So yes, discipleship, commitment to Christ and bearing one’s cross is essential.
Very nice, I believe these scriptures do define what is a disciple nicely.
So, can you be a Christian, and not a disciple? I think you can. In fact, I believe the parable of the soils is showing just that. Most folks believe the rocky soil and the thorny soil were not saved, but I disagree, Jesus said they believed, and anyone who believes is saved according to the word of God.
When they fell away, it does not say they are lost, it says they did not bear fruit. Big difference.
Luk 8:11 Now the parable is this: The seed is the word of God.
12 Those by the way side are they that hear; then cometh the devil, and taketh away the word out of their hearts,
lest they should believe and be saved.
13 They on the rock are they, which, when they hear, receive the word with joy; and these have no root,
which for a while believe, and in time of temptation fall away.
14 And that which fell among thorns are they, which, when they have heard, go forth, and are choked with cares and riches and pleasures of this life,
and bring no fruit to perfection.
15 But that on the good ground are they, which in an honest and good heart, having heard the word, keep it,
and bring forth fruit with patience.
Again, most folks think the rocky soil and the thorny soil are not saved, but look at verse 12 carefully, Jesus said if you believe you shall be saved.
Then note in verse 13 that the rocky soil only believed for a while. Nevertheless, they believed, and so according to verse 12 they are saved. But they bring no fruit to perfection.
The good soil are true disciples who keep God's word, and bring forth much fruit.
So, I believe that you can fail to be a disciple, yet be a believer and be saved. These persons that do not bring forth fruit will receive no rewards, yet they will be saved, so as by fire.
1 Cor 3:13 Every man's work shall be made manifest: for the day shall declare it, because it shall be revealed by fire; and the fire shall try every man's work of what sort it is.
14 If any man's work abide which he hath built thereupon, he shall receive a reward.
15 If any man's work shall be burned, he shall suffer loss: but he himself shall be saved; yet so as by fire.
My 2 cents.
