Matthew 7:15 says, Beware of false prophets, which come to you in sheep’s clothing, but inwardly they are ravening wolves.  There are many false prophets, or preachers and teachers, in the world today.  They proclaim another way to God other than by faith in Christ alone.  Some proclaim other gods, and some proclaim a modified gospel, adding to what is necessary to be saved, which is to be restored to a right relationship with God.  Anytime someone adds anything to the way to salvation other than Jesus Christ, crucified, resurrected, and Lord, then they are false prophets.  They may look like sheep, but they are really ravenous wolves.  We may be accused of being close minded by proclaiming that Jesus Christ is the only way to salvation, but this is one principal that cannot be compromised.  Verse sixteen says, Ye shall know them by their fruits. Do men gather grapes of thorns, or figs of thistles?  The only way that we as followers of Christ can bear fruit is by leading others to faith in Him as their Savior and Lord.  If we try to bear fruit by any other method, it will not be the fruit of the Holy Spirit.  Verse seventeen declares, Even so every good tree bringeth forth good fruit; but a corrupt tree bringeth forth evil fruit.  Jesus tells us that the good tree brings forth good fruit.  Jesus did not say that the good tree might possibly bring forth good fruit, but that it will bring forth good fruit.  Jesus expects us to be fruitful in reaching the lost world with His gospel.  By proclaiming the gospel of Christ alone can we bear fruit for Him.  Those who are rooted in any other religion or who add to salvation through Christ cannot bear good fruit.  Verse eighteen states, A good tree cannot bring forth evil fruit, neither can a corrupt tree bring forth good fruit.  Jesus tells us that if we are rooted in our faith in Him, if we are a good tree, then we cannot bring forth evil fruit.  If we are truly saved by faith in Christ, then we should be led by the Holy Spirit and will always proclaim Jesus Christ as the only way to salvation, which is the good fruit.  If someone bases their belief on anything other than salvation through Christ alone, then the can only bring forth evil fruit.  Verse nineteen declares, Every tree that bringeth not forth good fruit is hewn down, and cast into the fire.  This may not happen in this lifetime, but anyone who looks for salvation by any means other than by faith in Christ will ultimately be hewn down and cast into the fire.  Verse twenty states, Wherefore by their fruits ye shall know them.  Jesus tells us that we will be known by our fruits, so we have to ask what fruit are we bearing for Him.  I believe that as long as we are living by the leadership of the Holy Spirit and proclaiming Christ to the world that we are bearing fruit for Him, even if we don't always know it.  Verse twenty-one declares, Not every one that saith unto me, Lord, Lord, shall enter into the kingdom of heaven; but he that doeth the will of my Father which is in heaven.  This does not mean that someone who truly accepts Jesus and Savior and Lord will not go to heaven, but means that some who profess to follow Jesus do not truly put their faith in Him alone.  When we truly follow Jesus, we will do the will of the heavenly Father.  Verse twenty-two says, Many will say to me in that day, Lord, Lord, have we not prophesied in thy name? and in thy name have cast out devils? and in thy name done many wonderful works?  This implies that some people are going to be surprised when they are not admitted to heaven.  They will speak of the works they have done in Jesus' name, but salvation does not come from works, but from a relationship with Jesus Christ.  No matter how many good works we may do, if they are not done under the leadership of the Holy Spirit through our relationship with Jesus Christ, they are of no benefit to us spiritually.  Verse twenty-three says, And then will I profess unto them, I never knew you: depart from me, ye that work iniquity.  Just because a person proclaims to know Christ and does good things does not mean that person has a real relationship with Him.  We will be judged by our relationship with Christ, and nothing else.  Being a good person is not enough.
