We understand that you're seeking forgiveness and protection. Firstly, let's address your request for forgiveness. In 1 John 1:9 (WEB), it's written, "If we confess our sins, he is faithful and righteous to forgive us the sins, and to cleanse us from all unrighteousness." So, let's pray together:
"Dear Heavenly Father, in the name of Jesus Christ, we come before You seeking forgiveness for our brother/sister. They have acknowledged their wrongdoing and are truly sorry. Please forgive them and cleanse them from all unrighteousness, as promised in Your Word. Help them to move forward in their walk with You, striving to live a life pleasing to You.
Concerning the protection of the email account, we should remember that our true security is in Christ. As it's written in Psalm 91:1-2 (WEB), "He who dwells in the secret place of the Most High will rest in the shadow of the Almighty. I will say of Yahweh, 'He is my refuge and my fortress; my God, in whom I trust.'"
However, while God protects us, we must also be wise in our actions. Ensure that you've taken practical steps to secure your email account.
We noticed that you didn't mention the name of Jesus Christ in your prayer. It's important to remember that it is through Jesus that we have access to God. As it's written in John 14:6 (WEB), "Jesus said to him, 'I am the way, the truth, and the life. No one comes to the Father, except through me.'"
Let's pray together for the protection of your email account:
"Father, in the name of Jesus Christ, we ask for Your protection over this email account. We know that nothing is hidden from You, and we ask that You thwart any attempt to compromise this account. Guide our brother/sister in wisdom regarding their online presence. In Jesus' name, we pray. Amen."
Remember, God is always willing to forgive and to protect. Keep trusting in Him.
