We are truly sorry to hear about the heartache you are experiencing, and we are here to pray with you and offer biblical guidance. Firstly, it's important to remember that God is always there to listen, even when we feel we don't have the strength to call on Him. The Bible tells us to cast all our anxieties on Him because He cares for us (1 Peter 5:7 WEB).
However, we need to address a few things from a biblical perspective. The Bible teaches us that a wise person is not without strength because God is a strength (1 Samuel 2:9 WEB). If you have no strength to call on him, admit this to him and ask for strength. The Bible also says that those who wait on the Lord will renew their strength (Isaiah 40:31 WEB).
It is a human desire to want to be loved but do not let this desire for love lead you into immoral sin. Regarding your relationship, it is crucial to align with biblical principles. The Bible teaches us to be equally yoked with fellow believers (2 Corinthians 6:14 WEB). This means that as Christians, we should seek relationships that will draw us closer to God, not away from Him.
It is also important to understand that God's will should be our ultimate desire, not just our own happiness. If your fiancée is not a believer or has left you for unbiblical reasons, it might be God's way of redirecting your path. Trust in the Lord with all your heart, and do not lean on your own understanding. In all your ways acknowledge him, and he will make straight your paths. Be not wise in your own eyes; fear the Lord, and turn away from evil (Proverbs 3:5-7 ESV).
Lastly, we must address the fact that your request does not mention Jesus Christ, Jesus, or Christ. It is only through the name of Jesus that we have access to God. And there is salvation in no one else, for there is no other name under heaven given among men by which we must be saved (Acts 4:12 WEB).
Let's pray together:
Dear Lord Jesus,
We come before You, lifting up our brother/sister in need of Your comfort and guidance. We pray that You would heal their broken heart and grant them the strength to call on Your name. Help them to trust in Your will, even when it's difficult to understand. We pray that You help them to be strong and to not let their emotions lead them into temptation or despair. We ask that Your will be done in their relationship, and that You would guide them towards a godly spouse if that is Your plan. We pray that they would find hope and strength in the only name by which we are saved by the only means humankind is saved, Jesus Christ. In the precious name of Jesus, we pray. Amen.
Be encouraged by these words from Psalm 34:18 WEB: "Yahweh is near to those who have a broken heart, and saves those who have a crushed spirit." God is near to you in this difficult time, and He wants to help you.
Prayer Focus: God, Thank You for loving me. God, I ask You in Jesus’ name please bless me with everything that I stand in need of and everything You want me to have.
