You're the problem. (So am I.) God has given us promises in His word that we choose to ignore or discount. Here's an example: I used to believe I could pray for anyone and they'd get what I prayed for them. And it was happened. But, because I knew I was a sinner, God wouldn't hear my prayer. That's a double minded man. What happens to a double minded man?
James 1:6-8 (KJV)
But let him ask in faith, nothing wavering. For he that wavereth is like a wave of the sea driven with the wind and tossed. For let not that man think that he shall receive any thing of the Lord. A double minded man [is] unstable in all his ways.
Here's a very scary and truthful statement:
If you need faith to be saved, and when you have a need and you do not exercise faith that God will do as He's promised in His word for those walking in faith, how do you know you have enough faith to be saved? The just(tified) shall live by faith!
The devil has stolen the very thing Jesus gave us all, John 10:10. What happens to someone that kills another? Their blood is required of them, Luke 11:50. The devil thought that by killing Jesus he would be rid of Him and the devil would continue to rule the world. Jesus came in the flesh as 100% man. Yes, He was also 100% God, but He chose never to use His authority, John 8:28. He had to learn obedience, Heb 5:8. His actions were only based on the guidance of the Holy Spirit, period, Mat 4:1. When the devil killed an innocent Man, he forfeited his right to the universe, and Jesus took back what He gave Adam. What was it that Jesus gave us all as Christians? The Holy Spirit, John 7:39. The SAME Spirit He was guided by and He obeyed. So instead of eliminating Jesus and His power, the devil allowed Jesus to make His followers just like Him, living in faith, doing MORE than He did, John 14:12.
Enoch said we cannot please God without faith, Heb 11:6. If you have doubt then you have nothing to say to God, Heb 3:12, for He is a God of faith. You must have faith, believing in your heart, not your head, that He will give you all things, Rom 8:32.
So with all this information, you need to have faith and believe, Rom 4:21, that is a rewarder of them that DILIGENTLY seek Him, Heb 11:6. So let's say you start quoting the word of God for what you need, Psa 23:1, and you end it "if it be Your will." You're negating EVERYTHING you just prayed for! It IS God's will, or do you not believe the word of God.
Matthew 8:13 (KJV)
And Jesus said unto the centurion, Go thy way; and as thou hast believed, [so] be it done unto thee. And his servant was healed in the selfsame hour.
Matthew 19:26 (KJV)
But Jesus beheld [them], and said unto them, With men this is impossible; but with God all things are possible.
Matthew 21:21-22 (KJV)
Jesus answered and said unto them, Verily I say unto you, If ye have faith, and doubt not, ye shall not only do this [which is done] to the fig tree, but also if ye shall say unto this mountain, Be thou removed, and be thou cast into the sea; it shall be done. And all things, whatsoever ye shall ask in prayer, believing, ye shall receive.
So if you say "But I believe in my heart ALL these promises, but I still don't receive anything." Then it's still you!
Proverbs 28:13 (KJV)
He that covereth his sins shall not prosper: but whoso confesseth and forsaketh [them] shall have mercy.
Psalms 66:18 (KJV)
If I regard iniquity in my heart, the Lord will not hear [me]:
So whatever shall I do?
1 John 1:9 (KJV)
If we confess our sins, he is faithful and just to forgive us [our] sins, and to cleanse us from all unrighteousness.
CRY out to God!! He is the only One that can find that hindering sin.
Psalms 139:23-24 (KJV)
Search me, O God, and know my heart: try me, and know my thoughts: And see if [there be any] wicked way in me, and lead me in the way everlasting.
Doubt too is a sin, Rom 14:23.
Once I learned this, my life changed forever.
