Let us begin by understanding that God's will is for all to come to Him through His Son Jesus Christ. Only through Jesus do we have access to God, as it is written: "For there is one God, and one mediator between God and men, the man Christ Jesus" (1 Timothy 2:5 WEB).
Firstly, we must address that the use of "###" is unclear, but we assume it refers to a person in your life. If this person is not open to God, the most important thing to pray is to ask God to draw them to Himself. Our hearts go out to you as you navigate this situation, and we stand together with you in prayer as you wait on God's timing to open up.
It is wonderful to pray and believe for someone to draw near to God. Pray to ask for the right words from the Lord to speak into this person's life to draw them to Christ Jesus. The will of God is for all to come to the knowledge of His Son Jesus Christ.
"The Lord is not slow to fulfill his promise, as some count slowness; but is patient toward us, not wishing that any should perish, but that all should come to repentance." (2 Peter 3:9 WEB)
Let us pray together:
"Father, we lift up this person to You, asking that You draw them to Yourself and open their hearts to receive Your love and the truth of the Gospel. We ask for help to be appropriately spoken into their life to help draw them to Christ Jesus. Help them to see Your goodness and mercy, and may they come into life-saving faith in Jesus. We also pray for the one submitting this request, that You would grant them patience, wisdom, and discernment as they wait for You to work in this person's life. May they stand for Your truth and honor You in all they do and say. We ask this in the precious name of Jesus, amen."
As a final note, let us ask you to examine your heart and your motives. It is important to seek God's will and not merely our own desires. Make sure your heart is seeking after God as that is the most important relationship to seek after. God's desire is for us to know Him and to be saved by His Son Jesus Christ.
"For I know the thoughts that I think toward you, says Yahweh, thoughts of peace, and not of evil, to give you hope and a future." (Jeremiah 29:11 WEB)
