We understand that you're feeling remorseful for not responding to your friend's text, and it seems like she might be offended. First, let's remember what the WEB version of the Bible says in Matthew 5:23-24, "If therefore you are offering your gift at the altar, and there remember that your brother has anything against you, leave your gift there before the altar, and go your way. First be reconciled to your brother, and then come and offer your gift."
It's commendable that you're seeking to make things right. The first step is to acknowledge your mistake and apologize sincerely. Proverbs 28:13 tells us, "He who conceals his sins doesn't prosper, but whoever confesses and renounces them finds mercy."
Let's pray together:
"Father in heaven, we come before You in Jesus' name, lifting up our ### who seeks reconciliation with her friend. We pray that You would give her the wisdom and courage to approach her friend with a sincere apology. Soften her friend's heart to forgive and be willing to reconcile. Help them to communicate openly and restore their friendship, making it even stronger than before. In Jesus' name, we pray. Amen."
Remember, it's important to be patient and understanding as you approach your friend. Be clear in your apology and listen to her feelings. Also consider the example in Matthew 18:15, "If your brother sins against you, go, show him his fault between you and him alone. If he listens to you, you have gained back your brother." By approaching her privately and honestly, you're taking the right steps towards reconciliation.
Lastly, we commend you for praying in Jesus' name, as He Himself told us, "Most certainly, I tell you, whatever you may ask the Father in my name, he will give it to you." in John 16:23. Continue to trust in Him and follow His teachings.
