It is impossible to please God without faith. It doesn't matter what little worthless things you do in this life, which are considered "good" in the eyes of men. The wisdom of men is so much foolishness in the eyes of God.
“JESUS ANSWERED: AMEN, AMEN, I SAY TO THEE, UNLESS A MAN BE BORN AGAIN OF WATER AND THE HOLY GHOST, HE CANNOT ENTER INTO THE KINGDOM OF GOD.” (JOHN 3:5)
You must be baptized to enter heaven. If you have reached the age of reason then you must also believe in the essential truths (which are most fundamentally: the Incarnation and the Trinity) to have a valid baptism.
Mark 16:15-16- “And he (Jesus) said to them: Go ye into the whole world, and preach the Gospel to every creature. He that believeth and is baptized shall be saved: but he that believeth not shall be condemned.”
Again we see that you must be baptized AND believe to be saved. If you don't believe in Jesus Christ you will be condemned to hell.
Titus 3:5- “Not by the works of justice, which we have done, but according to his mercy, he saved us, by the laver of regeneration, and renovation of the Holy Ghost…”
Here we see again, by the laver of regeneration (baptism) we are saved.
Acts 2:37-38- “Now when they had heard these things they had compunction in their heart, and said to Peter, and to the rest of the apostles: What shall we do, men and brethren? But Peter said to them: Do penance, and be baptized every one of you in the name of Jesus Christ, for the remission of your sins: and you shall receive the gift of the Holy Ghost.”
You must be baptised and do penance for the remission of sins, you cannot be forgiven of your sins unless you are baptised and do penance. These sins are the things which will cause you to be condemned to hell.
Acts 16:26-33: Masters, what must I do, that I may be saved? But they said: Believe in the Lord Jesus, and thou shalt be saved... himself was baptized, and all his house immediately.”
