Once is not always enough. Can you receive all you need with a one time request of God? Of course the answer is yes, but it is not always that way. Sometimes, probably more than we want to admit, we need a second “touch” from the master.
What prompts a second or subsequent need to receive more from God than has been done? We must rest assured it is not cause by a power failure on God’s part. When Jesus “could do no mighty works” in His hometown it was not because He did not want to. It was not a lack of faith or power on His part. It was a lack of ability to receive all that was needed at the time.
There are many elements that affect our ability to receive the power of God. It could be a lack of faith, a lack of knowledge, disobedience, or a rash of other causes. We must press through our difficulties and grasp the promise we need at the moment. Ask and you will receive. Seek and you shall find. Knock and it shall be opened. It just might take more than one time.
