Isaiah 43:4; you are precious and honored in my sight.
Naturally when we get rejected by an individual or a group we tend to feel that we are perhaps inadequate or not up to standard or a particular task ahead. When it becomes continuous even the strongest in mind is bound to be very much affected.
There is a saying in my country that goes like, "when you are rejected somewhere you go somewhere else because in a world of many villages one should not sit at a place of shame". The truth is rejections will always exist, for Christians and Non-Christians alike how we respond to it will determine its effect on our lives.
For us Christians however, we are lucky to have one we look up to, now it may interest you to know and understand him, Christ was persecuted and rejected a lot of times in his lifetime on earth and so you are not an exception to this. But learn this too, Christ never stayed at where he is not wanted and so you should not too.
'So Go to where you are wanted, where you are valued and loved, where you will be appreciated so you can grow the talent and skill you have been imbibed with and always remember that you are precious to the Lord.
