Those not walking after the leading of the Holy Spirit based on God's Word ARE already condemned
Romans 8:13
For if ye live after the flesh, ye shall die: but if ye through the Spirit do mortify the deeds of the body, ye shall live.
Romans 8:1
There is therefore now no condemnation to them which are in Christ Jesus, who walk not after the flesh, but after the Spirit.
Galatians 5:16
This I say then, Walk in the Spirit, and ye shall not fulfil the lust of the flesh.
Ephesians 5:1
Be ye therefore followers (imitators) of God, as dear children;
Ephesians 4:22-24
put off concerning the former conversation the old man, which is corrupt according to the deceitful lusts;
And be renewed in the spirit of your mind;
And that ye put on the new man, which after God is created in righteousness and true holiness.
Romans 13:14
put ye on the Lord Jesus Christ, and make not provision for the flesh, to fulfil the lusts thereof.
Colossians 3:10
And have put on the new man, which is renewed in knowledge after the image of Him that created Him:
2 Corinthians 6:17
come out from among them, and be ye separate, saith the Lord, and touch not the unclean thing; and I will receive you.
I have the guidance of the Lord in this.
See scriptures above and note that God said these things.
One needs to stop hanging out with people that do drugs and drink and find some new friends.
Then we need to understand that God's Word is not only true, but He is upholding all things by the Word of His Power -
Hebrews 1:3
Those that want to be upheld in victory will stand on God's Word and not be moved from it, refusing to allow anybody talk them out of standing on what God says
The best example of how to do this is to go read in the Gospels about when the devil was trying to tempt Jesus to get Him to sin and notice that Jesus continually SPOKE God's Word because speaking God's Word out of your mouth forces your mind to shut up and listen to what your mouth is saying.
I used to walk around speaking God's promises of deliverance over and over which greatly helped me to renew my mind (I had addiction issues back in the day)
