Exodus 20 NKJV
7“You shall not take the name of the Lord your God in vain, for the Lord will not hold him guiltless who takes His name in vain.
Matthew 7 NKJV
21 “Not everyone who says to Me, ‘Lord, Lord,’ shall enter the kingdom of heaven, but he who does the will of My Father in heaven.22 Many will say to Me in that day, ‘Lord, Lord, have we not prophesied in Your name, cast out demons in Your name, and done many wonders in Your name?’ 23 And then I will declare to them, ‘I never knew you; depart from Me, you who practice lawlessness!’
Jeremiah 17 NVJV
above all things,
And desperately wicked;
Who can know it?
10 I, the Lord, search the heart,
I test the mind,
Even to give every man according to his ways,
According to the fruit of his doings.
Matthew 7 NKJV
16 You will know them by their fruits. Do men gather grapes from thorn bushes or figs from thistles?17 Even so, every good tree bears good fruit, but a bad tree bears bad fruit. 18 A good tree cannot bear bad fruit, nor can a bad tree bear good fruit. 19 Every tree that does not bear good fruit is cut down and thrown into the fire. 20 Therefore by their fruits you will know them.
Matthew 15 NKJV
8 ‘These people [c]draw
near to Me with their mouth,
And honor Me with their lips,
But their heart is far from Me.
24 “Strive to enter through the narrow gate, for many, I say to you, will seek to enter and will not be able. 25 When once the Master of the house has risen up and shut the door, and you begin to stand outside and knock at the door, saying, ‘Lord, Lord, open for us,’ and He will answer and say to you, ‘I do not know you, where you are from,’ 26 then you will begin to say, ‘We ate and drank in Your presence, and You taught in our streets.’ 27 But He will say, ‘I tell you I do not know you, where you are from. Depart from Me, all you workers of iniquity.’
3 I tell you, no; but unless you repent you will all likewise perish.
2 Corinthians 13
5 Examine yourselves as to whether you are in the faith. Test yourselves. Do you not know yourselves, that Jesus Christ is in you?—unless indeed you are disqualified.
