Things we consider certain can suddenly be whisked away. Our world is like a dune where the sand shifts and changes all the time but the Bible reminds us that in our shifting, sand dune world, God is the rock on which we can stand.
But if Christ is in you, although the body is dead because of sin, the Spirit is life because of righteousness… he who raised Christ Jesus from the dead will also give life to your mortal bodies through his Spirit who dwells in you. Romans 8:10-11
Just like the seeds of a plant, any seeds of kindness we sow will grow and spread. When we are kind to others, it encourages them to be kind to their fellow humans as well, therefore spreading seeds of kindness far and wide.
