We see immediately what is the first tactic that is employed. These are the adversaries of God’s people speaking and their first tactic is to feign friendship and common cause with the people of God.
This is a pattern of what happens to Christian people today and to the church. No sooner have you laid a foundation of something for Christ, than the opposition begins; the enemies of the faith become active. You begin a work of witness, wherever God has set you, in some new place, some new employment, new college. Wonderful! Your first act of witness, second act of witness – plain sailing! Everything is going well. Even the people who are not convinced by you, but are aware of what you are doing, seem to be very cordial towards you. Satan is sometimes caught out at first. But you have no sooner laid the foundation and then the opposition comes and the trouble, and somebody is raised up to make difficulties for you. The same happens with the church. You begin the work; everything goes well, and then the troubles start.
The Samaritans initially offer to rebuild alongside the Jews. Surely an extra hand will be welcome. Like the Judaising brethren in New Testament times, they want to insinuate themselves into the work, but really their approach is deceitful. Every infiltrator hides his true motive at first. It is the first approach because it is easier to infiltrate than to fight openly. It is easier to bring about change by subtlety than by outright confrontation. Nevertheless the goal is the same in both cases: to stop the work of the true church and to substitute something corrupt in its place. The liberal wants to bring about a counterfeit version of the gospel. So he tries to lure the church into cooperative evangelism. But the church must keep itself pure. Only the true gospel can advance the cause of Christ. As soon as we mix error with it, it becomes powerless. Always there are those who advocate mixed denominations, and often there are those who fall for this and are ‘in it to win it’. We fall for it again and again. Alliances, cooperation with those who don’t share the same love for Scripture, separation from the world, reverence for God.
