Who Is He?

I wish to share with my wife a passage from 1Peter. She has had to bear with a brother who seems hell bent on misunderstanding her, (and anyone who does not dot their i's properly). She and I have politly, but firmly asked him to leave us alone, but he seems to be a firebrand of discontent. "It is as sport to a fool to do mischief: but a man of understanding hath wisdom." (Prov. 10:23)

Here is the passage I wish to remind Rose of.

Finally, be ye all of one mind, having compassion one of another, love as brethren, be pitiful, be courteous: Not rendering evil for evil, or railing for railing: but contrariwise blessing; knowing that ye are thereunto called, that ye should inherit a blessing. For he that will love life, and see good days, let him refrain his tongue from evil, and his lips that they speak no guile: Let him eschew evil, and do good; let him seek peace, and ensue it. For the eyes of the Lord are over the righteous, and his ears are open unto their prayers: but the face of the Lord is against them that do evil. And who is he that will harm you, if ye be followers of that which is good? But and if ye suffer for righteousness' sake, happy are ye: and be not afraid of their terror, neither be troubled;But sanctify the Lord God in your hearts: and be ready always to give an answer to every man that asketh you a reason of the hope that is in you with meekness and fear:Having a good conscience; that, whereas they speak evil of you, as of evildoers, they may be ashamed that falsely accuse your good conversation in Christ.For it is better, if the will of God be so, that ye suffer for well doing, than for evil doing. (1 Peter 3:13-17 KJV)
