Acts 20:35 gives us a quote from the Lord Jesus saying, “It is more blessed to give than to receive.”
Giving back to God should be the most natural thing for us and never with the intent to get something in return. On the other hand, God has promised to take care of our needs as we honor him (Proverbs 3:9-10). See the circular relationship? You have to Love the Lord. We just received one of those surprise financial gifts. Thank you Jesus.
