We understand that you are seeking prayer for your three offspring to live long, healthy lives, and you have mentioned a special connection with someone named ###. Firstly, we would like to address the scripture you mentioned, Jeremiah 50:23. Let's look at it in context:
"How the hammer of the whole earth is cut apart and broken! How Babylon has become a desolation among the nations! I have laid a snare for you, and you are also taken, Babylon, and you weren't aware. You are found, and also caught, because you have struggled against Yahweh. Yahweh has opened his armory, and has brought forth the weapons of his indignation; for the Lord, Yahweh of Armies, has a work to do in the land of the Chaldeans. Come against her from the farthest border; open up her storehouses; cast her up as heaps, and destroy her utterly; let nothing of her be left. (Jeremiah 50:23-26 WEB)
The verse you mentioned is a part of a prophecy against Babylon, symbolizing godless and oppressive systems. It is not a verse to be claimed or prayed for personal purposes, but a declaration of God's judgment against the wicked.
Now, let us address your request for your offspring. We join you in praying for their well-being and long lives.
"Father in heaven, we come before you in the name of Jesus, lifting up the three offspring of the one who submitted this request. We pray that you would bless them with long and healthy lives, that they would grow strong in your love and wisdom. Protect them from all harm and danger, and guide them in the paths of righteousness for your name's sake. Help each one to be stolen from among the wicked and to follow Jesus Christ to eternal life. We ask this in accordance with your will, in Jesus' name.
Concerning your mention of a soulmate, we would like to remind you of 1 Corinthians 6:18:
"Flee sexual immorality! 'Every sin that a man does is outside the body,' but he who commits sexual immorality sins against his own body." (WEB)
The Bible teaches us to flee from sexual immorality, which includes any sexual relationship outside of marriage between a man and a woman. If your relationship with ### is not within the bounds of biblical marriage, we strongly encourage you to reconsider your relationship and choose to live in purity before God. Remember, God's design for marriage is a lifelong commitment between a man and a woman.
Lastly, we want to emphasize the importance of knowing Jesus Christ as your personal Lord and Savior. It is only through His name that we can approach God and be saved.
"For 'whoever will call on the name of the Lord will be saved.'" (Romans 10:13 WEB)
If you have not already, we encourage you to put your faith in Jesus Christ, confessing your sins and believing in His resurrection. This is the most important decision you can make for yourself and your loved ones.
We are here to help you grow stronger in your relationship with God and to help you have a stronger marriage and family. Please feel free to reach out again and keep us in the loop.
