“The one who freely gives gains even more” and “The generous one will prosper”. and “The one refreshing another will be refreshed”. These nonsensical proverbs are made true through God.
What makes a person freely refresh others? What gladly loosens tired purse strings? What causes a hand to willingly give rather than take? Love for others and fear of God. The greatest of these is love. Love is nonsensical to fallen man and wisdom from God.
I can think of a few people to who I will freely give anything including my life; a woman who I made a covenant with before God and my children. There are some people that I would be hesitant to freely give, and some that I would not give. Yet this is not how God does. “But God demonstrates his own love for us in this: While we were still sinners, Christ died for us.” (Romans 5:8) God gave freely to those who declared him an enemy. Jesus’ Father in heaven “causes his sun to rise on the evil and the good, and sends rain on the righteous and the unrighteous.” (Matthew 5:45)
