Satan hindered us.1 Thessalonians 2:18
Since the first hour in which goodness came into conflict with evil, it has never ceased to be true in spiritual experience that Satan hinders us. From all points of the compass, all along the line of battle, in the advance party or in the rear, at the dawn of day and in the midnight hour, Satan hinders us. If we work in the field, he seeks to break our implements; if we build a wall, he tries to cast down the stones; if we are serving God in suffering or in conflict—everywhere Satan hinders us. He hinders us when we are first coming to Jesus Christ. We had fierce conflicts with Satan when we first looked to the cross and lived. Now that we are saved, he tries to prevent our growth in Christian character. You may be congratulating yourself: “So far I have walked consistently; no one can challenge my integrity.”
Beware of boasting, for your virtue will soon be tested; Satan will direct his energies against the very virtue for which you are most famous. If you have to this point been a firm believer, your faith will soon be attacked; if you have been meek like Moses, expect to be tempted to speak unadvisedly with your lips. The birds will peck at your ripest fruit, and the wild boar will dash his tusks at your choicest vines.
Satan is sure to hinder us when we are faithful in prayer. He hinders our persistence and weakens our faith in order that, if possible, we may miss the blessing. Satan is equally vigilant in obstructing Christian effort. There was never a revival of religion without a revival of his opposition. As soon as Ezra and Nehemiah began to work, Sanballat and Tobiah were stirred up to hinder them. What then? We are not alarmed because Satan hinders us, for it is a proof that we are on the Lord's side and are doing the Lord's work, and in His strength we will win the victory and triumph over our adversary.
