Dear daughter,
I do understand and I know how such experience can be very painful and hurting especially when the guilty or the offender walk freely before you and throwing it right to your face, indirectly letting you know , you can't do nothing to me" hmmmm.. Very painful and emotionally hurtful. I had a similar experience two years ago. I gave an electrician a 5000 volt stabilizer worth up to 22 thousand naira plus a very expensive pressing iron worth 25,00-3000 Naira plus 2500 for repair. And yes, lest I forget , another one , I gave 1500 for carpentry work till today (two years still counting ) no stabilizer, no iron, no carpenter on sight not even my money. Now be the judge , what am I suppose to do as a man of God?
I may suggest, don't go about it violently but you may get some elderly people around or people and go to his work shop at least, for the recovery of your property. It is your right after all. Tell him he should forget the repair and return your property back to you.
You see, as Christians , being christ-like, walking on Christ's footstep is a whole lot of sacrifice you just can't fight or revenge his evil deed like every day or ungodly would. You must be guided and must not let your garment of righteousness get stained because of the things of the world. Your patient and humility was greatly put to test. But I do know God have something in store for you because he understands how traumatizing such experience can be.
He knows daughter, he sees it all.
Bless you.
