We understand your urgency and the deep longing of your heart. Firstly, we would like to commend you for ending your prayer in the name of Jesus Christ. It is only through His name that we have access to the Father, and there is no other name by which we can be saved. As it is written in Acts 4:12 WEB: "There is salvation in none other, for neither is there any other name under heaven, that is given among men, by which we must be saved!"
We can see the desperation and pain in your heart, and we want to lift you up in prayer and offer some biblical encouragement and advice. While God wants us to pour out our hearts to Him, it is important to align our desires with His will and timing. Psalm 37:4 WEB says, "Delight yourself also in Yahweh, and he will give you the desires of your heart." As you delight in the Lord, your desires will align with His will, and He will grant them in His perfect timing. In the WEB the word "Yahweh" is translated as "LORD" or "Lord".
Regarding your concerns about loneliness, singleness, and the desire for marriage, we want to encourage you to trust in God's timing and seek His will. It is important to pursue a godly spouse and a marriage that honors God, as outlined in the Bible. 1 Corinthians 7:39 WEB says, "A wife is bound by law for as long as her husband lives; but if the husband is dead, she is free to be married to whomever she wants to, only in the Lord."
We also want to address the issues of disappointment, rejection, criticism, delay, obstacles, misery, suffering, sadness, sorrow, misfortune, lack, and poverty that you mentioned. Remember that God works all things together for good for those who love Him and are called according to His purpose. Romans 8:28 WEB says, "We know that all things work together for good for those who love God, to those who are called according to his purpose."
As a group we will and encourage you to as well trust in God's timing and seek His will. Instead of focusing on the lack and negativity, let us as a group and you focus on praising God and thanking Him for His faithfulness and goodness. Philippians 4:6 WEB says, "In nothing be anxious, but in everything, by prayer and petition with thanksgiving, let your requests be made known to God."
Let us pray together:
"Dear Heavenly Father,
We lift up our brother to You, asking for Your will to be done in his life. We pray that You align his desires with Yours and grant them in Your perfect timing. We rebuke the spirits of loneliness, singleness, lateness in marriage, disappointment, rejection, criticism, delay, obstacles, misery, suffering, sadness, sorrow, misfortune, lack, and poverty in Jesus' name. We speak life, joy, peace, and abundance over his life. We ask You to perform miracles and wonders in his life. Help him and us be a man and women after Your own heart, seeking You first and trusting in Your timing.
In Jesus' name, we pray. Amen."
Be encouraged, and remember that God loves you and has a perfect plan for your life. Trust in Him, and He will never fail you according to His plan.
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.
