We understand your desire for a godly spouse and companionship, and we commend you for seeking God's will in this matter. Let us first address the issue of low self-esteem, as it is crucial to understand your value in God's eyes before he sends you a spouse that he has ordained.
In Christ's name, know this: you are fearfully and wonderfully made (Psalm 139:14 WEB). God knit you together in your mother's womb, and he has a purpose and a plan for your life. Your value is not determined by human standards but by God's love for you. He sent his Son to die for you, so that you might have life, and have it more abundantly (John 10:10 WEB). Low self-esteem is not from God; it is a lie from the enemy. God wants you to know that you are precious in his sight, and honored, and he loves you (Isaiah 43:4 WEB).
Now, regarding your request for a kingdom spouse, we pray that God will send you a godly spouse according to his will. We ask that you be patient and trust in God's timing. We encourage you to seek God first and his righteousness, and all these things will be added to you (Matthew 6:33 WEB).
We must also address that God's word is clear about the sanctity of marriage and the type of companionship we should seek. In 2 Corinthians 6:14 WEB, it is written, "Don't be unequally yoked with unbelievers, for what fellowship have righteousness and iniquity? Or what communion has light with darkness?" Therefore, we pray that God will send you a godly spouse who shares your faith and values, and who will build you up and encourage you in your walk with Christ.
You also mentioned that you want clear signs from both sides in the relationship. As Christians, we seek to know God's will through his word and prayer, so we will see signs of him answering our prayers. However, we also need to exercise wisdom and discernment, and seek godly counsel from our brothers and sisters in Christ, especially our godly older believers.
Finally, we want to remind you that it is only in the name of Jesus that we have access to God. It is written in John 14:6 WEB, "Jesus said to him, 'I am the way, the truth, and the life. No one comes to the Father, except through me.'" Therefore, we pray in accordance with his will, in Jesus' name.
Father, we lift up ### to you, and we ask that you heal their low self-esteem. Help them to see themselves as you see them, and to know their value in your sight. We ask that you will send them a godly spouse according to your will, in your timing. Help them to be patient and to trust in you. We ask that you will give them wisdom and discernment, and that you will guide them in your will for their life. We pray this in Jesus' name. Amen.
