Verses 1–4
Stumbling Blocks
The Lord warns His disciples of coming stumbling blocks. He says this in view of the Pharisees that are still under His hearing. These are the people who do not listen to Moses and the prophets, but to their own interpretations of them. However, they do call upon Moses and the prophets and that makes them so dangerous. Therefore the Lord warns His disciples of those who cause people to stumble.
He foretells them that there will be no escape from situations where they will face great temptations and deceptions that will test their faith in Him. If their eyes of faith are not constantly focused on Him, they will stumble and will follow such deceivers.
The Lord addresses His disciples in their responsibility. The words “woe to him through whom they come” are especially addressed to the religious leaders, who will try to prevent the disciples to follow a rejected Lord in His kingdom. He judges sharp about people who seem to serve God, but who are deceivers of those who want to follow Him in simple faith.
The Lord does not think only of the religious leaders. He also warns the disciples that they have to take care of themselves. A disciple is also capable of doing wrong things and can become a stumbling block for someone else. It is no excuse when we say that the other person is weak when he stumbles because of our behavior. It is precisely because this other person is weak that this must be a reason to help him and to make sure that we do not bring him to sin.
The stumbling block the Lord points to here, is the lack of willingness to go to a brother who sins. If we don’t go to him, the sinning brother is encouraged to think that sin doesn’t matter, and what will he fall into then?
Another stumbling block is that we do not forgive a brother who has sinned against us. If we tell others in detail about the sin that has been committed, it will be a stumbling block or blockade for forgiveness and restoration. We should not tell others what happened, but rebuke the brother in love. True brotherly love will convince the other of his sin, for through his sin the brother is not in fellowship with God, but in the power of satan.
If there is repentance, he must forgive his brother. He must let him know that it is good between him and God and between each other through his confession (1 John 1:9) and let him know this by having brotherly contact with him again (cf. 2 Corinthians 2:8). Cooled relationships by a done, but also confessed sin blocks real forgiveness.
Another stumbling block is to set a limit to forgiveness. The Lord points this out when He speaks of sinning “seven times”. The number, seven times, indicates that the other is completely wrong. The fact that everything happens in one day makes the test even greater. It is clear, however, that humanly speaking it is a hopeless case. Forgiveness does not seem to make any sense.
Then let us remember that in His indefatigable grace, God is thus dealing with us. If it wasn’t so, it would be completely hopeless for us, not only when we were still in our sins, but also now as believers. In the same way as God has dealt and acted with us, we must also deal with our brother.
