I think it likely is in response to the very open ended OP. When not knowing where to start, it is best to start at the Creeds (as a start, of course).
So I’ll say that I believe in all that is in the Nicene and Apostle’s Creed. I believe in the God the Creator, the Virgin Birth, the Resurrection of Jesus, the working of the Holy Spirit.
In addition to that, I believe in Theistic Evolution. I believe the Bible is divinely inspired (but not perfect). I believe that the Bible is man writing down a witness of his revelation, but in that biases can and do occur. I believe that the Bible is a process - where the understanding of God increased over time and one can see that in a God who seems be just a bigger, angrier version of us at times in Genesis becomes akin to a loving, welcoming God in the later Prophets, prior to the coming of Jesus himself.
I believe that God reveals Himself to us in ways we can understand Him (Calvin’s Theory of Condescension) and as we grow in understanding, God reveals more of Himself and that didn’t just stop with the Book of Revelation, but continues until today. I believe that when we were ready for it, God revealed His wish that slavery was not Godly and is currently revealing His wish that our homosexual brothers and sisters are welcomed into the Community of God, fully and with equal love and charity.
I believe that Jesus was the fulfillment of Old Testament prophecy. That God the Son became man so that man could rejoin with God. I believe that God became man so that the chains of sin, death, and the devil could be defeated in the sacrifice of Jesus Christ (my atonement is Christus Victor, not penal substitutionary - Christ’s sacrifice was a victory, not in payment for our sins). To jump off that, I believe that sin is merely moving away from God and since God is love, anything that is not loving is sinful.
I believe that God will save everyone in the end in His wonderful and matchless love.
I believe that Jesus began His Kingdom on the day He was resurrected, but it shall not full come into realization until His second coming. And yes, I believe he will come again to defeat evil.
I believe that at the end the dead will rise and there shall be a New Heaven and New Earth as stated in Revelation. I do not believe we will leave this Earth for a Heaven somewhere else - I believe that Heaven is simply God’s reality and in the end Heaven will transform the Earth into a new Eden.
My denomination is Lutheran (ELCA), but I believe that different denominations have different gifts. I believe the Holy Spirit is moving to this day and that speaking in tongues and healings can be manifestations of Its power (though I don’t think healings necessarily happen every day).
I also believe that God works on our hearts and emotions and am not troubled by those who claim miracles don’t make rational sense as God exists beyond rationality and beyond time and space.
I’m sure there are few more beliefs I have as a Christian, but that’s it for now :).
