In the business and materialistic view, one expects something in return for giving something, like payment. Well, that giving and taking also happens with love but it's not sought after; God gives back even more, a good return of investment. Of course the time depends on God alone.
While many of us belong in groups, we're all members of the human race, all in the same ship. There is no distinction at all. Jesus of Nazareth is not just for Christians, but for all people. God bless us all!
"Love your enemies and do good to them, and lend expecting nothing back; then your reward will be great and you will be children of the Most High, for he himself is kind to the ungrateful and the wicked. Be merciful, just as also your Father is merciful.
"Stop judging and you will not be judged. Stop condemning and you will not be condemned. Forgive and you will be forgiven. Give and gifts will be given to you; a good measure, packed together, shaken down, and overflowing, will be poured into your lap. For the measure with which you measure will in return be measured out to you." ~Jesus Christ (Luke 6:35ff NABRE)
