2 Corinthians 9:6
"Remember this: Whoever sows sparingly will also reap sparingly, and whoever shows generously will also reap generously."NIV
"But I say, He which soweth sparingly shall reap also sparingly; and he which soweth bountifully shall reap also bountifully. KJV
If we put our best purified drinking water in a container and fill it only part way, that is all we will have when we need good drinking water. If we fill as many containers as we can with our best water, we will have plenty of water to drink when we need it. The thing to remember here is that God is not talking about our own containers. He is referring to people who are in need of that which we have plenty. How much are we willing to give and how much will we insist on keeping for ourselves?
Heavenly Father, You have blessed us so much with many good things. We ask Your forgiveness for our selfishness. Give us tender, open hearts to give to those who are in need, not for the blessing You will give us, but for being conduits of Your love for the lost and needy. In Jesus' name, Amen.
