Luke 15:1 Then drew near unto him all the publicans and sinners for to hear him.
Publicans, despised tax collectors and sinners drew near to Jesus to hear him. Never resist the desire to get close to Jesus and to hear him. Often, other things call for our attention. In the story of Martha and Mary, Martha was busy doing good things, but the better thing Mary was doing. She was at the feet of Jesus.
Luke 10:41 And Jesus answered and said unto her, Martha, Martha, thou art careful and troubled about many things:
Luke 10:42 But one thing is needful: and Mary hath chosen that good part, which shall not be taken away from her.
Sinners should come to Jesus, for he came to set them free. We never are so noble and worthy that we do not need to come to Jesus, to hear of him. We shall do this forever. He is the Word of God. However some think they are already with knowledge and do not seek Jesus. instead they judge those who do. Be careful if you think you have arrived on a higher level than others and are become their judge.
Luke 15:2 And the Pharisees and scribes murmured, saying, This man receiveth sinners, and eateth with them.
They would never fellowship with sinners, although they were in truth sinners, perhaps more needy then them all. If we get to a place that we think we are too good to hear from Jesus or to witness to sinners for him, we need to repent. But are we not told to be separate from sin? We are not to be unequally yoked with unbelievers. Fellowship here means to partake with them in their sins. We do not join with sinners to sin. We come to them to bring Jesus, his light, his truth. Remember, if we are the salt, we keep sin from spreading, bringing the gospel to the lost so that they may escape the snare of the devil. What if they don't receive your words? We are called to sow the good seed of God's word. Some we harvest. If they mock you and want no part of Jesus, leave them and go to others. Others would wish to hear from Jesus, so go to these.
Gal 6:9 And let us not be weary in well doing: for in due season we shall reap, if we faint not.
