Be prepared to give and don't have a bad feeling about not helping then find yourself stuck in the sand needing help.
(1 John 3:7 KJV) Little children, let no man deceive you: he that doeth righteousness is righteous, even as he is righteous.
(Acts 20:35 KJV) I have showed you all things, how that so labouring ye ought to support the weak, and to remember the words of the Lord Jesus, how he said, It is more blessed to give than to receive.
