2 Timothy 3:12: Yea, and all that will live godly in Christ Jesus shall suffer persecution.
Before I suffered some minor persecution, I did not have very much assurance that I was saved. Since I have had some minor persecution, I have greater assurance that I am saved. If you have not suffered at least some persecution you are either not saved or you are not living godly. We should not seek to be persecuted or imagine that we have been. We should seek to live godly. One of the blessings that has accompanied persecution for me is assurance.
Matthew 5:11: Blessed are ye, when men shall revile you, and persecute you, and shall say all manner of evil against you falsely, for my sake.
One of the keys to knowing whether or not you have suffered true persecution is the word falsely. Have you deserved to be reviled or was it something you didn*t deserve? Have you brought it upon yourself? Have men said evil things about you that were true? Then you got what you deserved. You earned the reviling and the evil words.
Are you confident that whatever persecution you suffered was the will of God? Was it for something you said or did that was right?
1 Peter 3:17: For it is better, if the will of God be so, that ye suffer for well doing, than for evil doing.
Was there some strange happiness in you that accompanied or followed the persecution?
1 Peter 4:14: If ye be reproached for the name of Christ, happy are ye; for the spirit of glory and of God resteth upon you: on their part he is evil spoken of, but on your part he is glorified.
Did the persecution increase your resolve and your commitment to serve the Lord? Do you know that you are kept by the Lord when you are committed to do right things? Do you know that doing right things is a wonderful way to be safe and kept?
1 Peter 4:19: Wherefore let them that suffer according to the will of God commit the keeping of their souls to him in well doing, as unto a faithful Creator.
