If you give to others, you will be given a full amount in return. It will be packed down, shaken together, and spilling over into your lap. The way you treat others is the way you will be treated. Luke 6:38 CEV
As a child of God, God wants you to be a giver not just to others but also in His house. This is because as a giver, you are blessed and you don't lack anything.
When God wants to bless someone, He looks out for the one who has been giving and then goes ahead to bless that one.
The Bible says,
"Each of you must make up your own mind about how much to give. But don't feel sorry that you must give and don't feel you are forced to give. God loves people who love to give. God can bless you with everything you need, and you will always have more than enough to do all kinds of good things for others." 2 Corinthians 9:7-8 CEV.
God is ready to bless the giver till he has more than enough. He is always looking out for givers because He wants to bless an help them.
Also, the kind of giver you are and the kind of giving you do matters. If you want big harvests and big blessings, you must be a big giver, you must give lavishly.
2 Corinthians 9:6 CEV says,
"Remember this saying, “A few seeds make a small harvest, but a lot of seeds make a big harvest.”"
This means you have to plan your giving. Your pocket money shouldn't always be used for sweets and biscuits, you can set them aside for your giving in the house of God.
Make up your mind to be God's number one giver anywhere you are. Make the difference in and with your giving. Hallelujah!
