We understand that you're going through a difficult time with your feelings for this woman at your workplace. However, let's align our hearts with biblical principles.It is very important to know that we can only pray to God the Father in Jesus Name according to John 14.6.
Firstly, let's consider that God's Word tells us, Do not be unequally yoked with unbelievers. For what fellowship has righteousness with lawlessness? What communion has light with darkness? 2 Corinthians 6.14 This scripture tells us that our relationships should be with fellow believers in Christ. You did not mention if she is a Christian or not. If she is not, then you must put God first and chose to fellowship with Believers in Christ. You cannot have a true Christian marriage with an unbeliever.
The feelings you're experiencing are intense, but they should be godly and directed towards someone who shares your faith 1 Corinthians 15:33 Do not be deceived. Evil companionships corrupt good morals.
Secondly, it's crucial to guard our hearts, Proverbs 4:23 tells us, Keep your heart with all diligence, for out of it is the wellspring of life. Allowing our emotions to control us can lead to actions or thoughts that do not honor God. It's important to take control of your thoughts and bring them into captivity to the obedience of Christ 2 Corinthians 10:5. You said that you can't stop thinking about her and cant sleep well. These actions are not actions of a person who is trusting God. The Bible tells us not to worry about anything. But in every situation, through prayer and petition with thanksgiving, tell your requests to God. And the peace of God, which surpasses all understanding, will guard your hearts and your thoughts in Christ Jesus. Phillipians 4.6-7
Thirdly, the desire for the new person to leave so that you can have her affection is not a godly desire. We are called to love our neighbors as ourselves and to bless those who curse us Matthew 5:44. We should never wish harm or disadvantage on others for our own gain.
Lastly, let's pray together for God's will to be done in your life and for His peace to fill your heart.
Heavenly Father, we come before You, lifting up our brother in Christ. Lord, we ask for Your will to be done in his life. Help him to trust in You with all his heart and lean not on his own understanding Proverbs 3:5-6. Give him the strength to take every thought captive to the obedience of Christ. Help him to turn his eyes upon You, Jesus, and seek You first Matthew 6:33.
Lord, if it is Your will for this woman to be in his life, we pray for Your guidance and wisdom. Help them both to walk in Your truth and grow in Your grace. But if she is not your will for him, help him to release these desires and trust in Your plan for his life.
In Jesus' name, we pray for peace and comfort for our brother. Help him to sleep well and cast all his anxieties on You 1 Peter 5:7. Fill his heart with Your love and let him love others as You love us John 13:34.
Thank you, Father, for hearing our prayers.
In Jesus Name we pray.
