I know how difficult it can be to resist temptation, but one thing I have noticed is that by praying and reading the Word more, the stronger one becomes, kinda like building spiritual muscle. I will pray that the Lord would help you to persevere in prayer and imbibing of scripture and to unshackle you once and for all from this very damaging drinking habit; not just physically but spiritually.
"Nor thieves, nor covetous, nor drunkards, nor revilers, nor extortioners, shall inherit the kingdom of God." (1 Corinthians 6:10, Eng KJV +
This scripture is for your edification not condemnation, my friend. Never be offended by the Sword of God that cuts down the enemy like a laser beam through cotton wool.
May the Light of the world shine into your soul and scorch to ash all forms of bondage and leave with you the Peace of Christ!
"Peace I leave with you, my peace I give unto you: not as the world giveth, give I unto you. Let not your heart be troubled, neither let it be afraid." (John 14:27, Eng KJV +
