How I love this verse! First of all it begins using the word "confidence" in referring to prayer time. We can have confidence when we go to our Heavenly Father. He loves all of His children and wants only the very best for them. This confidence comes from a deep love. If I ask my husband to go to the store and pick up milk, I can be confident enough to know that he'll do just that. Well, if I trust this earthly man how much more can I trust the Divine man; God?
Secondly, it states the word "anything". Do you see that. ANYTHING! Anything I ask He will hear and listen. I am amazed that the Creator of the whole galaxy cares what I have to say. He wants to hear about any and every thing.
"His will". There's the rub. However, if I spend my time with Him and get to know Him as a Friend, Father, Redeemer, then I will know His will for my life and I will be able to ask with "confidence" and know that I am in "His will". He will hear and answer. Can you imagine that? If you were to call say the president and ask him to help you out in this finacial crisis that you are experiencing would he hear you, or even care? Probably not. But our Heavenly Father does care and will do anything we ask as long as it fits His plan. Who would you trust?
So ask with confidence and be sure you are in His will. He will hear you!
