Use Discernment!

With everything going on today, the Christian needs to be in the Word and using discernment. You have a number of cults who have totally rewritten the Bible so that it says what they want to hear. One such cult is the Jehovah's Witness. One way they have done this is to take away the Deity of Jesus Christ. The Mormons have the Bible but prefer to teach out of the Book of Mormon. God gave us specific warnings about altering His Word.
Revelation; 22:18-19
(For I testify to everyone who hears the words of the prophecy of this book: If anyone adds to these things, God will add to him the plagues that are written in this book; and if anyone takes away from the words of the book of this prophecy, God shall take away his part from the Book of Life, from the holy city, and from the things which are written in this book.)

In the second book of Peter, we are told that these false teachers will bring in destructive heresies even denying the Lord Jesus Christ. They come into the church with some form of teaching that sounds good, but when filtered through the Scriptures, we find it is wrong. This is why it is so tragic when a church makes a virtue out of tolerance for unscriptural teaching in the name of unity. One of these is sexual immorality. They want you to tolerate sexual immorality so that we can get along with each other. Take what is going on in California today. The people voted not to allow same sex marriages. Now they are rioting saying that the Christian right is not tolerant and they should be allowed to do what is forbidden in Scripture. God doesn't hate the homosexual, but He does hate the sin of homosexuality. We need to pray for them that they will turn from this immoral lifestyle.
Leviticus; 18:22
(You shall not lie with a male as with a woman. It is an abomination.)

How are we going to be discerning if we don't know what is in the Word of God. If we don't read and study God's Word, we leave ourselves open to deception. Anytime someone tells you that they have the only true way to worship God, filter it through the Scripture as see if it lines up. God has given us His Word so that we can be prepared for the false teachers. He doesn't send us to battle without the Sword of the Spirit which is the Word of God. As a good soldier, we need to be preparing ourselves for the battle ahead. As we get closer to the end times, the battles will increase in number and in intensity. Satan knows his days a numbered and he is fighting hard to destroy the church. Let's stand up for Jesus and what's right and not allow him any victories. We already know the outcome, because Jesus has won the battle.
Matthew; 16:18
(And I also say to you that you are Peter, and on this rock I will build My church, and the gates of Hades shall not prevail against it.)

Stand fast in your faith and thank God for the victory, for the battle belongs to the Lord.

God Bless You!
