To sum up most of my thinking it is good to start with Matt 6:25-33.
Who are you? It comes down to your priorities. Jesus said, “Seek first the kingdom of God.” Once you have that as priority number one, none of the other really matter. God’s Kingdom, His will, is the best for you. Who decides what we need and what we want? There should be no question of what is nice or hard or easy. Is it hard to follow God’s will? From whose perspective is it hard? Would it not be harder to go it your own way?
