Matthew 10:5 says, These twelve Jesus sent forth, and commanded them, saying, Go not into the way of the Gentiles, and into any city of the Samaritans enter ye not:  Jesus ordained the twelve.  If we are to be effective in spreading the gospel today, we must do so under the authority of being called by Christ.  We are not all called to be teachers and preachers, but we are all called for a purpose in God's kingdom.  When we all fulfill our purpose, the gospel will be spread much more effectively.  They were not to go to the Gentiles and Samaritans at this time, but were to go to the Jews first.  Verse six says, But go rather to the lost sheep of the house of Israel.  Jesus ordained them for a mission.  God still desired to work through His chosen people, and they were to be given another opportunity to be God's people in faith and not just in name.  Verse seven says, And as ye go, preach, saying, The kingdom of heaven is at hand.  If that was to be their message then, how much more so should it be our message today.  As we go about living each day, we should be spreading the gospel by our words and actions.  Verse eight states, Heal the sick, cleanse the lepers, raise the dead, cast out devils: freely ye have received, freely give.  Jesus told the disciples that by their faith in Him that they would be able to do the things that He had been doing.  I do not believe that Jesus's task for His followers only applied to the twelve disciples who were with Him then.  We still have this same commission today, but to be successful we can only carry it out by complete faith in the power of God.  Verse nine says, Provide neither gold, nor silver, nor brass in your purses,  This instruction meant that the disciples were to be totally reliant on God to meet their needs.  Too often Christians, or even churches, say that they feel God is leading them to do something particular, but that they will only go ahead once they are sure that they can afford to do so.  This is living by sight and not faith.  If we truly feel that God is leading us to do something, then if we follow in faith, He will provide the means.  Verse ten states, Nor scrip for your journey, neither two coats, neither shoes, nor yet staves: for the workman is worthy of his meat.  This is a continuation of the instruction in the last verse, with the addition of the statement that the workman is worthy of his meat.  Those who were being witnessed and ministered to should support those that God sent to them, and still should.  This does not mean to meet all their wants and desires, but to meet their basic needs.  Verse eleven says, And into whatsoever city or town ye shall enter, inquire who in it is worthy; and there abide till ye go thence.  The disciples were instructed that when they entered a city, they were to ask who could afford to let them stay with them.  Remember, these were Jewish people, God's chosen people, that the disciples were going to and they were going under God's command.  Verse twelve states, And when ye come into an house, salute it.  The disciples were to be respectful to those who allowed them to stay with them, and so should we be today to those who offer us support as we do God's work.  Verse thirteen says, And if the house be worthy, let your peace come upon it: but if it be not worthy, let your peace return to you.  I believe that this means that if the disciples were treated well that they should be at peace with the household, but if they weren't then they should not be troubled because of it.  Some people may have put them up out of a sense of obligation and have resented it.  Verse fourteen declares, And whosoever shall not receive you, nor hear your words, when ye depart out of that house or city, shake off the dust of your feet.  Jesus told the disciples that when people did not welcome them and hear their words, the gospel, that they were to leave and shake off the dust of their feet.  We cannot force anyone to receive the gospel, and if they will not hear and believe when we have shared it with them, we have done what God asks us to do.  Verse fifteen warns, Verily I say unto you, It shall be more tolerable for the land of Sodom and Gomorrha in the day of judgment, than for that city.  Sodom and Gomorrah were destroyed for the wickedness of their people, but Jesus said that those who refused to hear and accept the gospel would fare much worse.  They would go away into everlasting destruction having openly rejected salvation offered by Jesus.
