In 1.John 5:14-15, we read; 14 This is the confidence we have in approaching God: that if we ask anything according to his will, he hears us. 15 And if we know that he hears us—whatever we ask—we know that we have what we asked of him.
What does it mean to ask according to His will? The answer is found in 1.Pet 3:12 and proverbs 10:14, where it says Yehovah (God) only hears the prayers of the righteous. Who are the righteous? 1. John 3:7 says those who obey the law of Moses are righteous. So those who ask according to His will are the righteous, those who follow the law of Moses.
Those who follow the law of Moses are guaranteed to have their prayers hear, and because we know, He hears us, whatever we ask, we know that we have.
What do you need today? Whatever it might be, even if it is the desires of your heart (Prov 10:14), will be given if you ask in prayer obeying the law of Moses.
Does this mean you are guaranteed immediate healing, provision, and supernatural miracles? There are examples in the Bible of people who were given quick answers to prayers. Still, more examples of people had to wait for the answer to appear and remain in faith and obedience while they waited.
So whatever you need today, ask for it in prayer believing you have already received it because of your obedience to the law of Moses. If it is healing, believe you are already healed because you follow the law. If it is money, believe you are already provided for and well able to pay your bills because you follow the law. If you are not healed right away, and you still can not pay your bills, keep on standing on the promises of Yehovah (Deut 28:1-14, Matt 6:25-34), no matter what happens, declaring and believing you are healed and well able to pay your bills because you follow the law of Moses. Then you will be healed and provided for when the time is right, and while you wait for it to happen, Yehovah will care for you and meet your needs.
