Luke 17:6

And the Lord said, If ye had faith as a grain of mustard-seed, ye might say unto this sycamine tree, Be thou plucked up by the root, and be thou planted in the sea, and it should obey you.

The children of the world make it a point literally to scandalize, give offense with deliberate intent to hurt and to lead into sin. But among Christians it also happens, and frequently, that one brother offends the other, grieves him by some unpremeditated sin or in a moment of weakness. For that reason they should take heed, they should be on the lookout as regards themselves all the time, lest they themselves become guilty and scandalize a brother. And if a brother offends in any respect, the Christian that knows of the sin should earnestly admonish him, Matthew 18:21. As soon as the brother thereupon repents of his sin, the Christian should forgive him, fully and freely, even though the same process be repeated seven times a day. The heart of the believers should partake of the nature of God's and Christ's, or God's in Christ, which knows neither end nor limit. Whenever the confession comes: I am sorry, then should the assurance be given in return that the matter is forgiven. Such a. measure of love for the erring brother, it is true, requires an unusual amount of love, and therefore a corresponding amount of faith. The apostles were conscious of that fact; as matters stood then, they hardly believed themselves equal to the task proposed by Christ. And so, after mulling over the admonition for a while, they put the request to Him to add to their faith. This prayer is necessary for every Christian every day, if he wants his love to keep pace with the many demands that are placed upon it. Faith must grow at the same rate as love. A Christian will search ever more diligently, he will plunge ever more deeply into the depths of the love of God in Jesus the Savior. Only in that way will he be able to practice the forgiveness toward his brother which is demanded by the discipleship of Christ. The Lord took the occasion to enlarge upon one of His favorite topics, that of the strength of faith. If they had faith only as large as the seed of a mustard-plant or tree, they would have the power to say to the fig mulberry or sycamore fig-tree standing before them that it should tear itself out by the roots and plant itself in the sea, and it would obey without question. Note: To grow in faith, in the power of faith, must be the earnest ambition of every Christian. Sincere prayer to the Lord, unwavering trust in His promises, a constant contemplation of His Word: those are the methods by which growth in faith may be accomplished.
