We understand that you are going through a difficult time, and we are here to pray with you and offer guidance based on biblical principles.
Firstly, we want to address the urgency and desperation in your prayer. God cares about your needs and He hears your prayers. It is important to remember that God's timing is perfect, and He works all things together for good to those who love Him and are called according to His purpose. Trust in His timing and will for your life.
"Trust in Yahweh with all your heart, and don’t lean on your own understanding. In all your ways acknowledge him, and he will make your paths straight." Proverbs 3:5-6 WEB
Now, let's address the main issue of your prayer. You mentioned that someone has left and you will never see them again. We are not sure about the context, whether it is a friend, family member, or a spouse. We will assume it is a spouse or romantic interest since that is a common situation. If this is not the case, the general ideas here still apply. If you are married, we encourage you to pray for reconciliation if at all possible, as God desires that marriages be preserved, except in cases of unfaithfulness. God can work miracles and restore broken marriages. Seek God's help and obey His guidance in your life.
"For the unbelieving husband is sanctified in the wife, and the unbelieving wife is sanctified in the brother. Otherwise your children would be unclean, but now they are holy. Yet if the unbeliever departs, let there be separation. The brother or the sister is not under bondage in such cases, but God has called us in peace." 1 Corinthians 7:14-15 WEB
"Let marriage be held in honor among all, and let the marriage bed be undefiled; for God will judge the sexually immoral and adulterous." Hebrews 13:4 WEB
If you are not married, but were in a relationship with someone who has left, we encourage you to seek God's will for your life and trust that He has a plan and a purpose for you. It is important to pursue relationships that align with biblical principles, and to trust God with the future.
"Don’t be anxious about anything; but in everything by prayer and pleading with thanksgiving let your requests be made known to God. And the peace of God, which surpasses all understanding, will guard your hearts and your thoughts in Christ Jesus." Philippians 4:6-7 WEB
Remember that it is only in the name of Jesus that we have access to God. Jesus is the one who has saved us from our sins. We pray this in faith believing.
"for 'whoever will call on the name of the Lord will be saved.'" Romans 10:13 WEB
Let us pray together:
Dear Heavenly Father,
We come before You today, lifting up our dear brother/sister in Christ. Lord, they are going through a difficult time, and we ask for Your comfort and guidance to be upon them. We pray from your word, "Ask, and it will be given you. Seek, and you will find. Knock, and it will be opened for you" (Matt 7:7). We pray that you will renew their mind and help them to focus on You and Your will for their life. We pray that You, Lord, would do what is best for them and Your glory. We ask for a miracle for this situation in Jesus' name.
In Jesus' name, we pray. Amen.
