1 John 5:19-21
And we know that we are of God, and the whole world lieth in wickedness. And we know that the Son of God is come, and hath given us an understanding, that we may know him that is true, and we are in him that is true, even in his Son Jesus Christ. This is the true God, and eternal life. Little children, keep yourselves from idols. Amen.
Anything, any belief or any man that we put above the truth of God is an idol. If that thing distracts you away from the things of God, or that belief is contrary to the scriptures and the message Jesus brought, or if that man proclaims a message contrary to the truth; Lay it down, throw it away, turn away from that person. Let God be true and every man a liar (Rom 3:4)
Take fast hold of instruction; let her not go: keep her; for she is thy life. Enter not into the path of the wicked, and go not in the way of evil men. Avoid it, pass not by it, turn from it, and pass away. For they sleep not, except they have done mischief; and their sleep is taken away, unless they cause some to fall. For they eat the bread of wickedness, and drink the wine of violence. But the path of the just is as the shining light, that shineth more and more unto the perfect day. The way of the wicked is as darkness: they know not at what they stumble.
The wicked themselves are deceived, so they continue to deceive others…
Now I beseech you, brethren, mark them which cause divisions and offences contrary to the doctrine which ye have learned; and avoid them. For they that are such serve not our Lord Jesus Christ, but their own belly; and by good words and fair speeches deceive the hearts of the simple.
How can we be sure that we won’t be deceived, we should make sure that we LOVE THE TRUTH (Read the entirety of 2 Thessalonians chap 2) If we don’t love the TRUTH(Jesus Christ and all that He is and has proclaimed to the world)then we will fall for the lies of this world and anyone proclaiming the lies of this world.
Wherefore the rather, brethren, give diligence to make your calling and election sure: for if ye do these things, ye shall never fall…
