We understand your desire for protection and guidance in this new connection, and we will pray with you and on your behalf, and provide advice and correct any errors we see.
Firstly, we must address the fact that your note does not mention Jesus Christ or God. It is only by the name of Jesus that we have access to God, and there is no other name by which we can be saved. If either of you are not yet Christians, then we strongly encourage you to become a Believer in Jesus Christ. If you both are already Christians, then continue with the consolation of Jesus Christ in your life.
As you begin this new relationship, it's crucial to ensure that it aligns with biblical principles. We are deeply troubled that your courtship and our prayers are not focused on achieving a godly marriage and were started just after a previous relationship. The nature of your courtship and recent relationships suggests that you may not be approaching this new relationship in a biblical manner. Remember, the goal of any courtship should be to find a spouse, not simply to enjoy a fleeting emotional connection or casual relationship. Even if this does not lead to marriage, it will be painful if either of you do not have the consolation of Jesus Christ and His grace in your lives.
We must also address the fact that you mention living in a way that might suggest sexual immorality without specifically mentioning marriage. If you are living together or engaging in sexual relations outside of marriage, this is fornication or adultery and must be addressed, and repented for, and stopped immediately. It is written:
Flee sexual immorality. Every sin that a man does is outside the body, but he who commits sexual immorality sins against his own body (1 Corinthians 6:18 WEB).
Now, let us pray together:
Dear Heavenly Father,
We come before You in the name of Jesus Christ, lifting up this sister and the man she is getting involved with in their courtship. We pray that You will guide them according to Your will and that they are both Believers in Jesus Christ. We ask that You protect their hearts and emotions as they navigate this new connection. Help them to approach their courtship in a way that honors You. Help them to look towards a godly marriage rather than a fleeting emotional connection. If this is not Your will, then help them to both find Your grace in their lives and each other to remain friends. However, if they are meant to be married, help them to discern your will, and provide them the spiritual strength to pursue a godly relationship that ends in a godly marriage. In Jesus' name.
We encourage both of you to seek God's will in this new adventure. Trust in the Lord with all your heart, and do not lean on your own understanding. In all your ways acknowledge him, and he will make straight your paths (Proverbs 3:5-6 WEB).
May your courtship be guided by God's wisdom and love, and may it lead to a union that honors Him. May you both be sexually pure and remain sexually pure for the gift of marriage. May you both be Christians and follow Jesus Christ. We pray that all our relationships be centered on Jesus Christ and achieving a godly marriage.
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.
