Why do humans ask God for forgiveness and then go right back to doing what they asked for forgiveness for? Does God forgive us all the time even though it’s the same sin?

Matthew 16:13-23

13 Now when Jesus came into the district of Caesarea Philippi, he asked his disciples, “Who do people say that the Son of Man is?” 14 And they said, “Some say John the Baptist, others say Elijah, and others Jeremiah or one of the prophets.” 15 He said to them, “But who do you say that I am?” 16 Simon Peter replied, “You are the Christ, the Son of the living God.” 17 And Jesus answered him, “Blessed are you, Simon Bar-Jonah! For flesh and blood has not revealed this to you, but my Father who is in heaven. 18 And I tell you, you are Peter, and on this rock I will build my church, and the gates of hell shall not prevail against it. 19 I will give you the keys of the kingdom of heaven, and whatever you bind on earth shall be bound in heaven, and whatever you loose on earth shall be loosed in heaven.” 20 Then he strictly charged the disciples to tell no one that he was the Christ.

21 From that time Jesus began to show his disciples that he must go to Jerusalem and suffer many things from the elders and chief priests and scribes, and be killed, and on the third day be raised. 22 And Peter took him aside and began to rebuke him, saying, “Far be it from you, Lord! This shall never happen to you.” 23 But he turned and said to Peter, “Get behind me, Satan! You are a hindrance to me. For you are not setting your mind on the things of God, but on the things of man.”

Matthew 18:21-35

21 Then Peter came up and said to him, “Lord, how often will my brother sin against me, and I forgive him? As many as seven times?” 22 Jesus said to him, “I do not say to you seven times, but seventy-seven times.

23 “Therefore the kingdom of heaven may be compared to a king who wished to settle accounts with his servants. 24 When he began to settle, one was brought to him who owed him ten thousand talents. 25 And since he could not pay, his master ordered him to be sold, with his wife and children and all that he had, and payment to be made. 26 So the servant fell on his knees, imploring him, ‘Have patience with me, and I will pay you everything.’ 27 And out of pity for him, the master of that servant released him and forgave him the debt. 28 But when that same servant went out, he found one of his fellow servants who owed him a hundred denarii, and seizing him, he began to choke him, saying, ‘Pay what you owe.’ 29 So his fellow servant fell down and pleaded with him, ‘Have patience with me, and I will pay you.’ 30 He refused and went and put him in prison until he should pay the debt. 31 When his fellow servants saw what had taken place, they were greatly distressed, and they went and reported to their master all that had taken place. 32 Then his master summoned him and said to him, ‘You wicked servant! I forgave you all that debt because you pleaded with me. 33 And should not you have had mercy on your fellow servant, as I had mercy on you?’ 34 And in anger his master delivered him to the jailers, until he should pay all his debt. 35 So also my heavenly Father will do to every one of you, if you do not forgive your brother from your heart.”
