Sweet child, God is not angry at you, and if you knew His heart for you then you would not be angry at Him. Being angry at Him simply means you don't understand what is going on, you are hurting somehow, the confusion has made you think negative things about Him, and His heart is hurting for you even if you can't understand how that is possible. God IS love, He doesn't "do" love. He never stops loving you for any reason (1 John 4:8).
God the Son did not show up in the world through a woman, walk among evil men for 33 years, allow them to beat him until He could not be recognized, and nail Him to a wooden cross until He died in agony for you, all for you to think He cannot be trusted. No one dies for someone they do not truly love, and only He really truly loves you and stays with you even with your hard feelings toward Him. (John 15:13 - Genesis 16:13)
1 John 4:9-10
In this the love of God was manifested toward us, that God has sent His only begotten Son into the world, that we might live through Him. In this is love, not that we loved God, but that He loved us and sent His Son to be the propitiation for our sins.
1 John 4:19
We love Him because He first loved us.
God loved all of us before we ever loved Him back, and He is loving you right now even if you don't feel much love toward Him. God proved His insane love for you by sending His Son Jesus to die for you before you loved Him, not after (Romans 5:8).
Don't you know that Peter the disciple cursed and disowned the Lord Jesus practically to His face (Matthew 26:74)? Don't you know the Lord Jesus knew Peter was going to do that seeing as He told Peter in advance that he would do it (Matthew 26:34)? And do you know that the Lord Jesus was not only not mad at Peter at any time, but was praying to the Father and forgiving Peter in advance and loving Peter every moment before and after the event (Luke 22:32)?
Love does not count wrongs against it, and while there is a God of justice in Heaven, He sent His Son to die for you so that He could love you in spite of your mistakes.
1 Corinthians 13:5
Berean Standard Bible
It is not rude, it is not self-seeking, it is not easily angered, it keeps no account of wrongs.
Romans 8:32 says that if God gave His Son's life to us to save us, what will He not do for us?! God has made a solemn promise that He would not be angry at you (Isaiah 54:9) and God cannot lie (Hebrews 6:18).
No no, if you are angry at God it is because someone has whispered in your ear that He is not good and you are believing it somehow and in some way, but we know He is good. I think you know He is good, and I think you feel abandoned somehow, when He is always with you and never leaves you (Hebrews 13:5 - Matthew 28:20).
What I think you need to do, is be brutally honest with Him and have a talk. I think you need to give Him what you are carrying around and holding on tight to so He can fix it (1 Peter 5:7).
He already knows what you are thinking, what you are feeling, what is upsetting you exactly, and why you are holding on to it. He still has not left you, He still loves you, His heart is aching to help you and love on you, and He refuses to force you to come to Him. Love does not force people to come to them and interact with them against their will. You are His Child and He is hurting for you right now and wants to fix this for you.
He will never turn you away under any circumstances (John 6:37) and He will use all of this situation for your good (Romans 8:28).
If you are feeling condemned because of your feelings, know that you are not if you are in Christ (Romans 8:1) and that you never will be even if your heart is telling you such things (1 John 3:20).
Again, take your heart and everything you are feeling to Him and put one step in His direction, and you will know He is there and that He cares (1 Peter 5:7). Just talk to Him. You do not have a bad heart, just a hurting heart, and an afraid heart, and fear is a control mechanism used by the enemy. Don't let that keep you from the one that loves you with all of His being. You simply need to see how much He really loves you and when you do, and you listen in your heart to Him speaking to you, He will lift you up.
The fact it is bothering you shows He lives inside of you, do not doubt your conversion. Remember that you will always be His Child and no one can take you out of His hand, not even you (John 10:28).
I am praying for you.
Isaiah 54:10
For the mountains shall depart And the hills be removed, But My kindness shall not depart from you, Nor shall My covenant of peace be removed,” Says the LORD, who has mercy on you.
