Jude 3 (NKJV)

Jude 3 (NKJV)
Beloved, while I was very diligent to write to you concerning our common salvation, I found it necessary to write to you exhorting you to contend earnestly for the faith which was once for all delivered to the saints.

James 4:7-10 (NKJV)

James 4:7-10 (NKJV)
Therefore submit to God. Resist the devil and he will flee from you. Draw near to God and He will draw near to you. Cleanse your hands, you sinners; and purify your hearts, you double-minded. Lament and mourn and weep! Let your laughter be turned to mourning and your joy to gloom. Humble yourselves in the sight of the Lord, and He will lift you up.

Matthew 18:31-35 (NKJV)

Matthew 18:31-35 (NKJV)
So when his fellow servants saw what had been done, they were very grieved, and came and told their master all that had been done. Then his master, after he had called him, You wicked servant! I forgave you all that debt because you begged me. Should you not also have had compassion on your fellow servant, just as I had pity on you? And his master was angry, and delivered him to the torturers until he should pay all that was due to him.
So My heavenly Father also will do to you if each of you, from his heart, does not forgive his brother his trespasses.

Matthew 18:21-30 (NKJV)

Matthew 18:21-30 (NKJV)
Then Peter came to Him and said, Lord, how often shall my brother sin against me, and I forgive him? Up to seven times?
Jesus said to him, I do not say to you, up to seven times, but up to seventy times seven. Therefore the kingdom of heaven is like a certain king who wanted to settle accounts with his servants. And when he had begun to settle accounts, one was brought to him who owed him ten thousand talents. But as he was not able to pay, his master commanded that he be sold, with his wife and children and all that he had, and that payment be made. The servant therefore fell down before him, saying, Master, have patience with me, and I will pay you all. Then the master of that servant was moved with compassion, released him, and forgave him the debt.
But that servant went out and found one of his fellow servants who owed him a hundred denarii; and he lad hands on him and took him by the throat, saying, Pay me what you owe! So his fellow servant fell down at his feet and begged him, saying, Have patience with me, and I will pay you all.

Matthew 18:15-20 (NKJV)

Matthew 18:15-20 (NKJV)
Moreover if your brother sins against you, go and tell him his fault between you and him alone. If he hears you, you have gained your brother. But if he will not hear, take with you one or two more, that by the mouth of two or three witnesses, every word may be established. And if he refuses to hear them, tell it to the church. But if he refuses to hear the church, let him be to you like a heathen and a tax collector.
Assuredly, I say to you, whatever you bind on earth will be bound in heaven, and whatever you loose on earth will be loosed in heaven.
Again, I say to you that if two of you agree on earth concerning anything that they ask, it will be done for them by My Father in heaven. For where two or three are gathered together in My name, I am there in the midst of them.

Ephesians 5:22-30 (NKJV)

Ephesians 5:22-30 (NKJV)
Wives, submit to your own husbands, as to the Lord. For the husband is the head of the wife, as also Christ is head of the church; and He is the Savior of the body. Therefore, just as the church is subject to Christ, so let the wives be to their own husbands in everything.
Husbands, love your wives, just as Christ also loved the church and gave Himself for her, that He might sanctify and cleanse her with the washing of water by the word, that He might present her to Himself a glorious church, not having spot or wrinkle or any such thing, but that she should be holy and without blemish. So husbands ought to love their own wives as their own bodies; he who loves his wife loves himself. For no one ever hated his own flesh, but nourishes and cherishes it, just as the Lord does the church. For we are members of His body, of His flesh and of His bones.

Exodus 34:14 (NKJV)

Exodus 34:14 (NKJV)
For you shall worship no other god, for the LORD, whose name is Jealous, is a jealous God.
