And I will give unto thee the keys of the kingdom of heaven: and whatsoever thou shalt bind on earth shall be bound in heaven: and whatsoever thou shalt loose on earth shall be loosed in heaven. – Matthew 16:19
In this earth realm, there is always a part that we have to play first before God does His part. We can always “start something” with God that He will finish. This principle applies to your finances too. When you sow seed, God will send the harvest. But, God can’t do your part if you don’t do yours. And it is also true that you can’t do God’s part. Your only responsibility is to do your part and then trust and believe that God will do His. Receiving from God is a divine cooperation.
When you search the scripture, you will see that all the blessings and promises of God are conditional upon our doing something in connection or cooperation with those promises. If there are any areas of your life where you feel like you are not receiving the promises and blessings of God like you should, ask yourself, am I doing my part?
