Faith in Christ alone
Believe on the Lord Jesus Christ and thou shalt be saved.
And they said, Believe on the Lord Jesus Christ, and thou shalt be saved, and thy house. And they spake unto him the word of the Lord, and to all that were in his house. — KJV, Acts 16:31-32
Verily, verily, I say unto you, He that believeth on me hath everlasting life. — KJV, John 6:47
Believe on the Lord Jesus Christ and you are eternally saved, once saved always saved, not of works, lest any man should boast..
Jesus said unto her, I am the resurrection, and the life: he that believeth in me, though he were dead, yet shall he live: And whosoever liveth and believeth in me shall never die. Believest thou this? — KJV, John 11:25-26
For many shall come in my name, saying, I am Christ; and shall deceive many. — KJV, Matthew 24:5
Dont trust those who name his name
Now when he was in Jerusalem at the passover, in the feast day, many believed in his name, when they saw the miracles which he did. But Jesus did not commit himself unto them, because he knew all men, And needed not that any should testify of man: for he knew what was in man. — KJV, John 2:23-25
Once you have been saved, I suggest that you buy yourself a real king james bible. The oxford 1833 reprint of the king james bible. Proper understanding of the scripture can help you in this life and also in terms of eternal rewards.
Read the new testament of it for an hour per day.
Reading the old testament on top of that and listening to the kjv audio bible is good as well.
Let yourself be rebuked by the scripture.
