What does a man gain when he has the whole world in his possession and loses his life.
In Mathew 6:19 , we are told not to lay up for ourselves treasures on earth. The verses 20 tells us to instead lay up for ourselves treasures in heaven.
One would as " how are we going to eat , clothe ourselves and care for our body?". From the verses 25 going , we told not to be anxious about our life. For the birds neither sow nor reap nor gather into barns yet they fed by the Father. For even Solomon in all his glory was not arrayed like on of these.
In verse 32 and 33, we get to know that our heavenly Father knows that we need all these thing(clothes...). So we are told to seek first His Kingdom and His righteousness , and all of these things shall be yours as well.
