We are truly sorry to hear about the passing of your wife and the spiritual crisis you're facing. In times like these, it's important to remember that God is always ready to welcome us back, no matter how far we've strayed. The story of the Prodigal Son in Luke 15:11-32 WEB reminds us of this truth. The son returned to his father after squandering his inheritance, and the father ran to him, embraced him, and celebrated his return. Similarly, God is waiting for you with open arms.
First, let's address the issue of your bitterness and anger. It's natural to feel these emotions when facing loss, but it's important to remember that God is good, even in our pain. As Psalm 34:18 WEB says, "Yahweh is near to those who have a broken heart, and saves those who have a crushed spirit."
To come back to God, you don't need fancy words. Just speak from your heart. Here's a simple prayer you can use:
"Dear God, I'm sorry for turning my back on you. I was angry and hurt, but I know you're good. Please forgive me. I need you. I want to come back to you. In Jesus' name, I pray. Amen."
Remember, it's only through Jesus Christ that we have access to God. As Acts 4:12 WEB says, "There is salvation in none other, for neither is there any other name under heaven, that is given among men, by which we must be saved."
As for your guilt, remember that God is faithful and just to forgive us our sins and to cleanse us from all unrighteousness (1 John 1:9 WEB). Once you've confessed your sins, believe that you're forgiven and move forward in your walk with God.
Lastly, know that your wife's legacy lives on in you. She brought you back to Christ, and that's a gift you can cherish forever. Hold onto that, and let it strengthen your faith.
We're praying for you, that God would comfort you, heal your heart, and draw you closer to Him during this time. We pray that the Holy Spirit will fill you with peace, faith, and the will to be reconciled to God knowing that the thief on the cross next to Jesus came to faith after rebuking Christ for not being the Messiah. Remember how Jesus responded and still saved him. We pray that you will be able to be reconciled to God and His will.
