The fact that you don’t drink alcohol, smoke and fornicate does not make you a Christian, it is through faith in Christ that we Christians. There are sins of the heart which we don’t see with the physical eyes. A relationship with God is a heart issue.
Galatians 3:19 Why, then, was the law given? It was given alongside the promise to show people their sins. But the law was designed to last only until the coming of the child who was promised. God gave his law through angels to Moses, who was the mediator between God and the people.
Following the law does not guarantee us salvation, it is through believing Jesus Christ that we are saved. Galatians 3:22,27 But the Scriptures declare that we are all prisoners of sin, so we receive God’s promise of freedom only by believing in Jesus Christ. And all who have been united with Christ in baptism have put on Christ, like putting on new clothes.
One cannot have have Christ in him but continue with his old ways. Christ in us will help us move away from sin.
There are people who the devil doesn’t have to work hard to use them because they choose to continue with their old self. Sometimes we even boast about our weaknesses. When I’m angry, I’m like this..I will show him/her..Acknowledge your weakness and ask God to help you where you can’t. Colossians 3:8-10 But now you yourselves are to put off all these: anger, wrath, malice, blasphemy, filthy language out of your mouth. Do not lie to one another, since you have put off the old man with his deeds, and have put on the new man who is renewed in knowledge according to the image of Him who created him.
There are things we can do on our own and there are those that we must give to God. Refuse the devil at all cost and don’t allow him to use for his purpose. James 4:7-8 Therefore submit to God. Resist the devil and he will flee from you. Draw near to God and He will draw near to you. Cleanse your hands, you sinners; and purify your hearts, you double-minded.
Colossians 4:5-6 Walk in wisdom toward those who are outside, redeeming the time. Let your speech always be with grace, seasoned with salt, that you may know how you ought to answer each one.
Hebrews 5:12-14 For though by this time you ought to be teachers, you need someone to teach you again the first principles of the oracles of God; and you have come to need milk and not solid food. For everyone who partakes only of milk is unskilled in the word of righteousness, for he is a babe. But solid food belongs to those who are of full age, that is, those who by reason of use have their senses exercised to discern both good and evil.
Jesus expect each believer to grow to the level where he can teach others. Paul encourages us to be grounded and built in Christ. Colossians 2:6-7 As you therefore have received Christ Jesus the Lord, so walk in Him, rooted and built up in Him and established in the faith, as you have been taught, abounding in it with thanksgiving.
Deuteronomy 10:16 Therefore, change your hearts and stop being stubborn.
If you not strong in your spiritual life, try to separate yourself from those outside. You’ll either change them or they will change you. 2 Corinthians 6:14-16 Don’t team up with those who are unbelievers. How can righteousness be a partner with wickedness? How can light live with darkness? What harmony can there be between Christ and the devil? How can a believer be a partner with an unbeliever? And what union can there be between God’s temple and idols? For we are the temple of the living God. As God said: “I will live in them and walk among them. I will be their God, and they will be my people.
