God will never have a bad day, He is not subject to the circumstances to determine whether He is in a good or bad mood.

Of course God doesn’t have "moods", He is God and He is self-sufficient, He is love, peace, joy, He does not practice them, these feelings are what He is. God cannot help being love, joy, peace...

One might wonder why so much anger, violence in the Old Covenant?
Would God have changed?
No, the Bible says that God does not change, He is love.
God has begun a plan to redeem the human beings immediately after the fall of Adam and Eve. Since that day He has never stopped to make sure His plan can continue, so that humans can have as today this opportunity to be born again, and enter into a transformation to become like Jesus.
We could not explain all of the examples of the old Covenant where we can read about the anger of God, we recommend for more information about this to read our study on the personality of God.

Since the cross, God spiritually eradicated sin of the human being, we now have a relationship with Him based on a mutual love.

Hebrews 10: 22  let us draw near with a true heart in full assurance of faith, having our hearts sprinkled from an evil conscience and our bodies washed with pure water.

Romans 8: 1   There is therefore now no condemnation to those who are in Christ Jesus, who[a] do not walk according to the flesh, but according to the Spirit.

These passages show us that God does not condemn us, but not only that... No matter what the circumstances are, God will always be in an attitude to encourage me to move forward in the transformation of my being to become love like He is love.
Too often Christians consider God with human reactions, but God is constant in all His ways. You can never do anything to make God angry because His anger is not against humans, but against sin, and His anger has nailed sin to the cross. It is a fact that no one can change, the sin has been decimated at the cross, as well as the wrath of God toward humans. Once sin destroyed, God does not feel anger against His children because that same sin has been eradicated.

God is not disappointed as a man can be, He's not picked nor disillusioned about you.
What He wants is that His children understand that they have an open access to Him at all times.
God does not sulk His children because they would not have a life according to His word.
Of course acting outside what God advocates us, is very harmful for us, we suffer all the human consequences of our sins, but in no case God will keep His distance with you, because you have messed up and have sinned. He will not agree with what you have done or said, but He is always ready to welcome you, help you change in order to avoid doing it again. He never gets tired to love us, to help us...

God does not have bad days, because if that were the case, we just need to look at what is happening on Earth every day, to see that God would have every possible reason to be in a bad mood, but He is not.

Romans 6: 1-4 What shall we say then? Shall we continue in sin that grace may abound?  Certainly not! How shall we who died to sin live any longer in it?  Or do you not know that as many of us as were baptized into Christ Jesus were baptized into His death? Therefore we were buried with Him through baptism into death, that just as Christ was raised from the dead by the glory of the Father, even so we also should walk in newness of life.

Paul shows us in this passage that is out of question to take advantage of the fact that God forgave us all, to make the most of this forgiveness by sinning without restraint.
If you are born again, your old self has been buried with Jesus and you are now a new person walking in a new life led by the nature of God in you.
In order to see this accomplished in a tangible way in your life, you simply need to believe it firmly by activating your faith. In the same way you believe without a doubt that you are saved, believe you are this new person according to the nature of God which is already within you. Think about it throughout the day, act upon that same thought...

Don't think that God is keeping His distance with you because you have sinned ; get close to Him at all times spontaneously. The fact of regretting and not wanting to do it again proves your good faith.
Satan wants you to believe that there are times where God does not want to see you, that He is disappointed.

But God will always be in a right frame of mind toward you, this is a fact that nobody can change.

Bye for now.
