Christian means "Christ-like". Knowingly sinning is not "Christ-like". Will people unlike Christ enter into the Kingdom of God? Friends, the defiled will not enter into God’s Kingdom, so we must be diligent with our lives to be real servants of Jesus Christ. We must look to the power in Jesus’ blood to set us free from anything that defiles us.Sinning, knowingly or otherwise doesn't mean you're not a Christian or that you lose your Christianity.
Revelation 22
[10] And he saith unto me, Seal not the sayings of the prophecy of this book: for the time is at hand.
[11] He that is unjust, let him be unjust still: and he which is filthy, let him be filthy still: and he that is righteous, let him be righteous still: and he that is holy, let him be holy still.
[12] And, behold, I [Jesus] come quickly; and my reward is with me, to give every man according as his work shall be.
[13] I am Alpha and Omega, the beginning and the end, the first and the last.
[14] Blessed are they that do his commandments, that they may have right to the tree of life, and may enter in through the gates into the city.
[15] For without are dogs, and sorcerers, and whoremongers, and murderers, and idolaters, and whosoever loveth and maketh a lie. 16I Jesus have sent mine angel to testify unto you these things in the churches. I am the root and the offspring of David, and the bright and morning star.
Revelation 21
[6] And he said unto me, It is done. I [Jesus] am Alpha and Omega, the beginning and the end. I will give unto him that is athirst of the fountain of the water of life freely.
[7] He that overcometh shall inherit all things; and I will be his God, and he shall be my son.
[8] But the fearful, and unbelieving, and the abominable, and murderers, and whoremongers, and sorcerers, and idolaters, and all liars, shall have their part in the lake which burneth with fire and brimstone: which is the second death.
