Wherefore gird up the loins of your mind, be sober, and hope to the end for the grace that is to be brought unto you at the revelation of Jesus Christ; As obedient children, not fashioning yourselves according to the former lusts in your ignorance: But as he which hath called you is holy, so be ye holy in all manner of conversation; Because it is written, Be ye holy; for I am holy.
You want a book on Heaven, pick up God’s Word and not fall to the fantasy of men.
For if he that cometh preacheth another Jesus, whom we have not preached, or if ye receive another spirit, which ye have not received, or another gospel, which ye have not accepted, ye might well bear with him. For I suppose I was not a whit behind the very chiefest apostles. But though I be rude in speech, yet not in knowledge; but we have been throughly made manifest among you in all things.
For such are false apostles, deceitful workers, transforming themselves into the apostles of Christ. And no marvel; for Satan himself is transformed into an angel of light. Therefore it is no great thing if his ministers also be transformed as the ministers of righteousness; whose end shall be according to their works.
Then said Jesus unto his disciples, If any man will come after me, let him deny himself, and take up his cross, and follow me.
The only way of salvation is found through a personal relationship with the Lord Jesus Christ. God has provided a way of salvation, a right relationship with Him, and a means of forgiveness. “Jesus saith unto him, I am the way, the truth, and the life: no man cometh unto the Father, but by me” (John 14:6). “And saying, The time is fulfilled, and the kingdom of God is at hand: repent ye, and believe the gospel” (Mark 1:15).
And as he sat upon the mount of Olives, the disciples came unto him privately, saying, Tell us, when shall these things be? And what shall be the sign of thy coming, and of the end of the world? And Jesus answered and said unto them, Take heed that no man deceive you. For many shall come in my name, saying, I am Christ; and shall deceive many. And ye shall hear of wars and rumours of wars: see that ye be not troubled: for all these things must come to pass, but the end is not yet. For nation shall rise against nation, and kingdom against kingdom: and there shall be famines, and pestilences, and earthquakes, in divers places. All these are the beginning of sorrows. Then shall they deliver you up to be afflicted, and shall kill you: and ye shall be hated of all nations for my name’s sake. And then shall many be offended, and shall betray one another, and shall hate one another. And many false prophets shall rise, and shall deceive many. And because iniquity shall abound, the love of many shall wax cold.
