We understand your concern about the delay in your future plans with your fiancée, JeffJ. Let us first align our hearts with God's will and remember His words in Isaiah 40:31 (WEB), "But those who wait for Yahweh will renew their strength. They will mount up with wings like eagles. They will run, and not be weary. They will walk, and not faint."
In your prayer, you mentioned trusting and believing in the Lord, but we noticed that you didn't mention the name of Jesus Christ. It's crucial to acknowledge that our prayers are heard because of Jesus' sacrifice for us. As it's 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.'" Let's uplift your concerns in Jesus' mighty name.
Let us pray together:
"Dear Heavenly Father, we come before You in Jesus' name, lifting up our brother JeffJ. Lord, he seeks Your strength to trust and believe in You amidst delays in his future plans with his fiancée. We ask that You grant him unwavering faith and patience, knowing that Your timing is perfect. Remind him that even in delays, Your plan is at work. In Jesus' name, we pray. Amen."
While waiting, consider the words of Psalm 37:7 (WEB), "Rest in Yahweh, and wait patiently for him. Don’t fret because of him who prospers in his way, because of the man who makes wicked plots happen."
Lastly, we encourage you, JeffJ, to continue trusting in the Lord with all your heart, and lean not on your own understanding. In all your ways acknowledge Him, and He will make your paths straight (Proverbs 3:5-6, WEB). Keep pursuing a God-honoring marriage, and may the Lord bless your union in His perfect timing.
