I didn't say I wouldn't—God said this to me one day after asking Him about my promise that He made to me. —I didn't say I wouldn't, He had my attention. After pondering that a few seconds, I realized I heard Him say that before. He was trying to tell me something and I hadn't given it my attention. What Lord, I said, what are you saying to me? He said I didn't change My mind, I didn't say I wouldn't keep My promise. Then He reminded me of my last assignment. He said, when you do that for Me I am excited to do this for you! 

God tells us throughout His Word. If we do His will then we will have the fulfillment of His blessings and He will do what He said He would do. I needed reminding of my part of His will I was instructed to do for Him.
So often many think God said no and clearly, He is not saying no to His children whom He adores. What He has said is we have a part in our relationship with Him. As His children, He needs our love as well as we need His. It is not a take only relationship, but giving (loving God) is required of us to keep our relationship with God a strong and healthy relationship.
How is loving God doing our part? By partaking in our relationship with Him, not just asking God to give us a favor, but to find out who God is and partake in His life —which is loving the Lord your God with all your heart, soul, and mind, the first and most important command because He is our sustenance. He is our daily bread and without Him, we can do nothing!

Most often we have this thinking we can rush to God when we need something, get it, run back home, and then the next time we have a need —run again. As well, each time we go to God we’re a little older and our requests seem a little more intense. Now we have no idea whether He will say yes or no, so we beg and have massive prayer chains going on because we don't actually know what He is thinking because we failed to follow through with that loving commitment. We don’t know if He will say yes or no, so we hope and pray that someone can get through to Him for us.

If one took the time to know God and follow through with that love commitment and would actually move in with Him and partake in what His life is about, then they wouldn't have to run back and forth in their crisis of trying to find someone to reach Him for them. If you know Him and live in His Kingdom, you can just talk to Him and find out how much He loves you and then come in agreement with Him. Now when things are not happening the way He promised, you can just ask Him where you missed it.   

James 1:5 If any of you is deficient in wisdom, let him ask of the giving God [Who gives] to everyone liberally and ungrudgingly, without reproaching or faultfinding, and it will be given him. AMPC

I never go to God to tell Him He missed it because first of all, He is God and He is in love with me and is excited to do good for me. Next, I am learning of Him, not Him of me. — I am learning how to fit into His Kingdom He is not learning mine.

Galatians 6:9 And let us not lose heart and grow weary and faint in acting nobly and doing right, for in due time and at the appointed season we shall reap, if we do not loosen and relax our courage and faint. AMPC

Many assume we are waiting on God to reap those good things, but the thing is, He is waiting on us to go to Him and be in that relationship with Him and find out what is going on from Him. Due time is as long as it takes us to seek Him and learn to live in His will (Kingdom)—that is up to us not Him. It is up to me to be in agreement with Him. He is waiting for me to do what I said I would do, and He is excited while He waits for that due season to do for me!

He isn't hard to find, He is already knocking at the door of your heart just waiting for you to invite Him in and heed His voice so that He can teach you how to live in His Kingdom and bring all those blessings to come to pass in your life.

Revelation 3:20 Behold, I stand at the door and knock; if anyone hears and listens to and heeds My voice and opens the door, I will come into him and will eat with him, and he [will eat] with Me. AMPC

Jesus said when we live in agreement with Him then we can ask what we will and it will be granted to us, as representing Him. That means as you learn His way and agree with Him —you qualify for all His blessings. You won’t have to have a massive prayer chain to ask Him for a favor—you can ask Him yourself because you know Him and talk with Him every day. Then —you will hear Him reward you Himself with those Words spoken to you in your heart coming right straight from His. 

John 15 I am the True Vine, and My Father is the Vinedresser.2 Any branch in Me that does not bear fruit [that stops bearing] He cuts away (trims off, takes away); and He cleanses and repeatedly prunes every branch that continues to bear fruit, to make it bear more and richer and more excellent fruit. 3 You are cleansed and pruned already, because of the word which I have given you [the teachings I have discussed with you]. 4 Dwell in Me, and I will dwell in you. [Live in Me, and I will live in you.] Just as no branch can bear fruit of itself without abiding in (being vitally united to) the vine, neither can you bear fruit unless you abide in Me. 5 I am the Vine; you are the branches. Whoever lives in Me and I in him bears much (abundant) fruit. However, apart from Me [cut off from vital union with Me] you can do nothing. 6 If a person does not dwell in Me, he is thrown out like a [broken-off] branch, and withers; such branches are gathered up and thrown into the fire, and they are burned. 7 If you live in Me [abide vitally united to Me] and My words remain in you and continue to live in your hearts, ask whatever you will, and it shall be done for you. 8 When you bear (produce) much fruit, My Father is honored and glorified, and you show and prove yourselves to be true followers of Mine.
