(Galatians 5:24) "Moreover, those who belong to Christ Jesus impaled the flesh together with its passions and desires"
The introductory line from the bible leaves no gray area: if you belong to Christ, you have crucified the body with attachments and lusts. Then why are some Christians still trying to crucify the body? This is because Satan lied to them and they believe it because they did not know the Word of God themselves.
Satan could have mocked you by saying, "If you were truly a true Christian, you would not have lie yesterday!" This should not immediately weaken your self-confidence and dispel your faith and enthusiasm to serve the Lord. Remember who Satan is - a liar and a father of lies.
He is the deceiver and accuser of God's people (Revelation 12:10). If your hands have been lifted up in worship of the Lord, and Satan has suddenly reminded you of something you have done wrong, do not suddenly drop them and start crying with pity. Instead of bowing even more, say, "Father, thank you for your love and the blood of Jesus Christ, who cleanses me from all injustice."
Never let Satan cheat and think that you are not a true Christian because of what you did wrong in the past. If you are born again, you are a true Christian. The Word of God says that your nature is God who is in you. Walk in Spirit and in righteousness. Live according to the word of God, for this is your life.
Occasionally say to yourself, "I am of the Spirit, and the Word rules and guides me." Study and keep the word of God, and you will live above Satan’s manipulations, maneuvers, and deceptions. The more you study, listen, and meditate on the Word of God, the more you walk, as the Word warns. This is because the Word has the power to produce in you what it speaks of. Through the ministry of the Word you are encouraged, strengthened, your faith is moved, and you are constantly growing in Christ. The more you grow in the Lord, in the grace and knowledge of His Word, the less sin you will find in your life; for sin will not rule over you (Romans 6:14).
Dear Father, I thank you for your word, which is useful to me in teaching doctrine, reproach, correction, the teaching of righteousness that leads me to spiritual growth and encourages my faith in good works. I am rooted and entrenched in the Word, showing the virtues and perfection of the Spirit in the name of Jesus. Amen.
