Whatever we share and are generous with, it will multiply. If we hide it or hoard it, it will wither and die.
If we share because we want to get more, that isn't real good sharing. That is sharing with an agenda and I don't think God blesses that kind of generosity. I wouldn't even call it generosity.
And we are to share our talents and skills with others, to build others up. If we do it just to get ahead it might work but it will be a hollow success and not that satisfying after the hype goes away. But if we do it in love for others, we will experience such joy. Our lives will be enriched.
Anything we are given we can share: finances, gifts, talents, skills, family, time, holidays, emotions. Anything that benefits our life can be shared with others.
Ask God to help you see those you can benefit today, those you can help. Often, it only takes a few minutes, a few dollars, not much to make an impact if you share it with your heart, just because with no thought of receiving anything in return.
