Have you ever told yourself negative things? The Lord wants to build each one of us with positive words. Check out these scriptures in the bible which challenge our negative thoughts of self.
The Lord and His word also encourages us to do the same for each other.
So why not try speaking some of these positive words of scripture over yourself and your brothers and sisters the next time a negative thought enters your head, so that we encourage and build each other up in love and confidence just as Jesus asked us too.
