"But understand this, that in the last days there will come times of difficulty. For people will be lovers of self, lovers of money, proud, arrogant, abusive, disobedient to their parents, ungrateful, unholy, heartless, unappeasable, slanderous, without self-control, brutal, not loving good, treacherous, reckless, swollen with conceit, lovers of pleasure rather than lovers of God, having the appearance of godliness, but denying its power. Avoid such people."
--- 2 Timothy 3:1-5
And though the last days will be an arduous time for believers, when we walk in the Spirit, we find that the sinful appetites of the flesh have no more dominion over us.
Those who walk in the Spirit will rely on the Holy Spirit to guide them in thought, word, and deed
(Romans 6:11–14).
They show daily, moment-by-moment holiness, just as Jesus did when,
"full of the Holy Spirit, [He] left the Jordan and was led by the Spirit into the wilderness"
to be tempted
(Luke 4:1).
Those who walk in the flesh will be vulnerable to taking the mark of the beast.
And the most defenseless will be alcoholics, drug addicts, gambling addicts, shopping addicts, and the like who will not have the self-control to prevent selling their souls to the devil.
For these, hopelessness and despair will abound.
So, watch and pray and let your mind dwell on Christ.
(Philippians 4:8)
so you will not fall into temptation.
(Matthew 26:41)
For those who live according to the flesh set their minds on the things of the flesh, but those who live according to the Spirit set their minds on the things of the Spirit.
For to set the mind on the flesh is death, but to set the mind on the Spirit is life and peace.
For the mind that is set on the flesh is hostile to God, for it does not submit to God's law; indeed, it cannot. --- Romans 8:5-7
That is why it is so important to read and meditate on scripture. It makes you God-focused and your
mind is set upon the Lord instead of the flesh.
