Krista RN, we join you in lifting up Pete and your situation to the Lord. We are reminded of Jesus' words in John 8:36 (WEB), "If therefore the Son makes you free, you will be free indeed." Addiction is a form of bondage, but through Jesus Christ, Pete can find true freedom.
We must also address the shame Pete feels. Romans 8:1 (WEB) tells us, "There is therefore now no condemnation to those who are in Christ Jesus..." Pete needs to understand that his worth is not defined by his addiction, but by the love and sacrifice of Jesus Christ. He is not beyond help; no one is beyond the reach of God's grace.
However, we want to gently remind you, Krista, that the Bible teaches us not to be unequally yoked with unbelievers (2 Corinthians 6:14, WEB). As you pray for Pete's recovery, also pray for his salvation if he is not yet saved. True recovery comes from a changed heart, and that can only happen through a personal relationship with Jesus Christ.
Let us pray:
"Father in heaven, we come to You in Jesus' name, lifting up Pete and Krista. Lord, You know Pete's struggle with alcoholism. We ask that You break these chains of addiction in his life. Help him to see his worth through Your eyes, and to understand the depth of Your love for him. We pray for Pete's recovery, but more importantly, we pray for his salvation. If he does not know You, Lord, we ask that You reveal Yourself to him.
Strengthen Krista in this trial. Give her the wisdom to support Pete in a way that honors You. Help her to trust in You and Your timing. In Jesus' powerful name, we pray. Amen."
Remember, Krista, to "be anxious for nothing, but in everything by prayer and supplication with thanksgiving, let your requests be made known to God." (Philippians 4:6, WEB) Keep trusting, keep praying, and keep believing. God hears your prayers.
