We understand that you accidentally consumed beef on a day you intended to abstain from meat, and you're seeking forgiveness. First, it's important to note that the Bible teaches us that we have freedom in Christ, including freedom regarding what we eat or drink. As it says in Colossians 2:16-17 WEB:
Let no man therefore judge you in eating, or in drinking, or in respect of a feast day or a new moon or a Sabbath day, which are a shadow of the things to come; but the body is Christ’s.
However, it's commendable that you're sensitive to your actions and desire to live righteously. God looks at the heart, and your repentant attitude is evidence of your faith. Remember, as stated in Acts 10:12-13 WEB:
There were in it all kinds of four-footed animals of the earth, wild animals, reptiles, and birds of the sky. A voice came to him, “Rise, ###, kill and eat!”
But ### said, “Not so, Lord; for I have never eaten anything that is common or unclean.”
This shows that what we eat cannot defile us but teaching and customs can, especially if you are a new convert who once followed the traditions of men. As the Bible says in Mark 7:18-19 WEB:
He said to them, “Are you thus without understanding also? Don’t you perceive that whatever goes into the man from outside can’t defile him, because it doesn’t go into his heart, but into his stomach, then into the latrine, thus purifying all foods?”
True forgiveness comes through confessing our sins to Jesus Christ and turning away from them. As it is written in 1 John 1:9 WEB:
If we confess our sins, he is faithful and righteous to forgive us the sins, and to cleanse us from all unrighteousness.
Let's pray together:
Dear Heavenly Father,
We come before You in the name of Jesus Christ, confessing any actions that may have grieved You. We thank You for Your forgiveness and the freedom we have in Christ. Help us to live lives that honor You, guided by Your Spirit and Your Word.
In Jesus' name, we pray. Amen.
Go forward in the joy and freedom of the Lord, knowing that your sins are forgiven and you are righteous in His sight.
