Of course i believe that, and no im not saying we should all sing kumbaya. What truth should we hold onto though?
Jesus is the way the truth and the life. But this would be the Jesus revealed in the Holy Scriptures and not a Jesus of our own imagining. Jesus and his followers gave us certain teachings within Scripture for us to have faith in and to follow.
Again, some of things I already mentioned are requirements according to the Word of God.
I will name them again (with a few more).
You should believe and defend (and be separate from other believers if necessary over the following truths):
1. The Trinity.
2. Jesus is God.
3. Sola Scriptura.
4. All men must first accept Jesus as their Savior and believe that He died and was risen on our behalf to gain entrance into God's kingdom and be initially saved.
5. God is love and God is good.
6. God does not directly create evil or cause people to be a certain way.
7. God does not tempt man to sin.
8. We are to obey God's commands within the New Testament in this life as a part of our faith (i.e. to love God and to love others).
9. Repentance. Believers cannot sin and still be saved. They have to be honestly sorry about their sin and forsake it. They cannot justify sin and evil and think they are in God's good graces.
10. Without faith, it is impossible to please God.
11. Faith without works is dead.
12. Without holiness, no man shall see the Lord.
There are more, but this should help give you an idea of certain truths that you should defend in God's Word that I believe are essential to the faith; And defending the faith will cause division amongst other professing believers.
