We understand your burden for your boyfriend and we join you in prayer, standing on the promises of God.
Firstly, we commend you for praying in Jesus' name, as it is only through Him that we have access to the Father (John 14:6, "Jesus said to him, 'I am the way, the truth, and the life. No one comes to the Father, except through me.'").
However, we must address that the Bible encourages us to be equally yoked with fellow believers (2 Corinthians 6:14, "Don’t be unequally yoked with unbelievers, for what fellowship have righteousness and iniquity? Or what communion has light with darkness?"). As you pray for him, we hope that your boyfriend is also a believer striving to live according to God's will.
We pray for your boyfriend, that God may deliver him from the bondage of cocaine, insecurities, lust, and pornography. These are strongholds that can be broken only through the power of Jesus Christ (2 Corinthians 10:4, "For the weapons of our warfare are not of the flesh, but mighty before God to the throwing down of strongholds.").
Pray with us:
"Father, we lift up this man to you, asking for his deliverance from these bondages. Renew his mind, Lord, according to your word (Romans 12:2, 'Don’t be conformed to this world, but be transformed by the renewing of your mind, so that you may prove what is the good, well-pleasing, and perfect will of God.'). Help him to resist temptation and find his strength and identity in you (1 Corinthians 10:13, 'No temptation has taken you except what is common to man. God is faithful, who will not allow you to be tempted above what you are able, but will with the temptation also make the way of escape, that you may be able to endure it.'). In Jesus' name, we pray. Amen."
We also pray for your relationship, that it may glorify God and be a testament to His love and faithfulness. We encourage you both to seek godly counsel and to remain in fellowship with believers who can support and encourage you in your walk with Christ (Hebrews 10:24-25, "Let us consider how to provoke one another to love and good works, not forsaking our own assembling together, as the custom of some is, but exhorting one another, and so much the more as you see the Day approaching.").
Lastly, we encourage you to trust in God's timing and will for your relationship. Be patient and seek His guidance in every step (Proverbs 3:5-6, "Trust in Yahweh with all your heart, and don’t lean on your own understanding. In all your ways acknowledge him, and he will make your paths straight.").
