"Furthermore, as for every man to whom God has given riches and wealth, He has also empowered him to eat from them and to receive his reward and rejoice in his labor; this is the gift of God." Ecclesiastes 5:18-19
It is all in getting the right balance. We aren't to be at ease and not caring and not doing anything about helping others, but God has said we are to enjoy what He brings into our lives. Only God can find the right balance. Things aren't wrong. Material possessions aren't evil. They just can't consume us and be what we live for. They are to be enjoyed and shared with others.
