Just as the Lord will use people to bless you, the enemy will attempt to use people to curse you. In these days you must discern the orgins of those who desire to ingratiate themselves into your lives. Actions speak louder than words. Anyone can say anything, but actions (fruits) bear out the truth of the source. Be watchful and prayful that you not fall prey to those sent of the enemy.
II Timothy 3:
1BUT UNDERSTAND this, that in the last days will come (set in) perilous times of great stress and trouble [hard to deal with and hard to bear].
2For people will be lovers of self and [utterly] self-centered, lovers of money and aroused by an inordinate [greedy] desire for wealth, proud and arrogant and contemptuous boasters. They will be abusive (blasphemous, scoffing), disobedient to parents, ungrateful, unholy and profane.
3[They will be] without natural [human] affection (callous and inhuman), relentless (admitting of no truce or appeasement); [they will be] slanderers (false accusers, troublemakers), intemperate and loose in morals and conduct, uncontrolled and fierce, haters of good.
4[They will be] treacherous [betrayers], rash, [and] inflated with self-conceit. [They will be] lovers of sensual pleasures and vain amusements more than and rather than lovers of God.
5For [although] they hold a form of piety (true religion), they deny and reject and are strangers to the power of it [their conduct belies the genuineness of their profession]. Avoid [all] such people [turn away from them]. (AMP)
