We are thrilled to hear that you are seeking a godly relationship and that the person you are interested in has been instrumental in your spiritual journey. It is wonderful that you are considering this relationship with a focus on Christian principles.
First, let's remember the words of Psalm 37:4, Trust in Yahweh, and do good. Dwell in the land, and enjoy safe pasture. Also delight yourself in Yahweh, and he will give you the desires of your heart.
Commit your way to Yahweh. Trust also in him, and he will do this:
he will make your righteousness go forth as the light, and your justice as the noonday.
Rest in Yahweh, and wait patiently for him. Do not fret because of him who prospers in his way, because of the man who makes wicked plots happen.
Cease from anger, and forsake wrath. Do not fret, it leads only to evildoing.
For evildoers shall be cut off, but those who wait for Yahweh shall inherit the land.
Yet a little while, and the wicked will be no more. Yes, you will diligently look for his place, and he will not be there.
But the humble will inherit the land, and will delight themselves in the abundance of peace. Psalm 37:5-11 WEB
It is important to approach this confession with prayer and a heart that is open to God's will. Remember that God's timing is perfect, and His plans are always for your good. As you confess your feelings, do so with honesty, respect, and kindness.
We also encourage you to consider the principles of courtship, where the goal is to seek God's will and discern if marriage is the right path for both of you.
Let's pray together:
Dear Heavenly Father in Jesus Name,
We come before You, lifting up our brother in Christ who is about to confess his feelings to someone special. We thank that You have used this person to draw him closer to You. We pray that You will guide his words and actions, giving him the courage and wisdom he needs. We ask for Your will to be done in this situation.
Help Him to remain strong in his faith to accept Your will whether it is the answer he is looking from or not. We ask that help him and the other person to grow in your Word and remain friends if marriage is not Your will. We ask that the other person will be respectful and kind when responding.
We also pray that he will continue to trust in You, knowing that Your plans are always good.
In Jesus' name, we pray. Amen.
We encourage that You leave this situation with the Lord. The other person should not be your main focus, but the Lord should. May this situation continue to draw you closer to the Lord.
