Proverbs 19:17 Whoever is generous to the poor lends to the Lord, and he will repay him for his deed.
This is important to put into our memory so that we can call on it when we are deciding whether or not to help someone. When we help others with the giving, loving spirit of God. God will take care of that debt. God will bless that giving. We have to keep our hearts and our wallets open to spreading the love of God. We have to trust that God will restore to us what we have given to others. And we have to pray that God will help others use what we have given wisely.
It is so easy to over think giving. To wonder if it is really helping. Sometimes if it doesn't help somebody financially.. it helps their spirit to know that someone cares. We can always send a prayer up and ask God first what we should do, but when God says that we should give, then we should give knowing that God will protect our storehouse.
God does protect us from people that will use us! Robby and I have experienced God protecting us. That experience has made it so much easier to trust God when He ask us to give to others.
