I'm sorry, I can't be perfect, but I expect you to be

The problem of being good is that it lifts you up and put others down. Every Christian should be careful when they are good. It is their weakest moment when pride puffs up and judges their weaker brother.

Assurance

Our assurance - God is faithful

God is faithful, by whom ye were called unto the fellowship of his Son Jesus Christ our Lord. (1 Corinthians 1:9 KJV)

There hath no temptation taken you but such as is common to man: but God is faithful, who will not suffer you to be tempted above that ye are able; but will with the temptation also make a way to escape, that ye may be able to bear it. (1 Corinthians 10:13 KJV)

Faithful is he that calleth you, who also will do it. (1 Thessalonians 5:24 KJV)

Moreover whom he did predestinate, them he also called: and whom he called, them he also justified: and whom he justified, them he also glorified. (Romans 8:30 KJV)

Being confident of this very thing, that he which hath begun a good work in you will perform it until the day of Jesus Christ: (Philippians 1:6 KJV)

The Message of the Quran

The message of the Quran is this: "God is great. Submit to Him". The Taurat (Torah), Zabur (Psalms) and Injil (Gospel) also contain this message, but their main message is that of redemption of God's people. It is this message of redemption that makes Taurat (Torah), Zabur (Psalms) and Injil (Gospel) special and consistent in their outlook.

The Quran has no message of redemption. Its message is general, telling us the obvious.

The consistent message of the God of Abraham in the Bible

The consistent message of the God of Abraham in the Bible is deliverance. God promised the the Israelites in Egypt that He will deliver them from bondage in Egypt. He will bring them to the Promised Land. Likewise, God promised the Christians deliverance from the bondage of sin. He will bring us to the Heaven of Eternal Rest.

The means of deliverance is also consistently the same - Redemption. God redeemed the people of Israel during the Passover night by the blood of the Passover lamb. God redeemed Isaac also by a ram caught in a thicket by his horns (Genesis 22:13). God redeemed us by our Lord Jesus, who is our Passover Lamb (John 1:29).

It is for this reason the Old Testament and the New Testament can co-exist in one volume, called the Bible - the consistency of the same message.

Moses Established Criteria For Future Prophets

Moses as the first prophet to write a book set the standard for all future prophets. He also made a prediction for the special prophet - "I will raise them up a Prophet from among their brethren, like unto thee, and will put my words in his mouth; and he shall speak unto them all that I shall command him (Deuteronomy 18:18)." Some claimed that "among the brothers" means that the Prophet will not be an Israelite, but from his brother. Well, Esau is the brother of Israel and I have not seen any significant Edomite prophet. But I have seen a descendant of Israel's uncle, Ishmael, claiming to be a prophet, but Deuteronomy 18:18 rule him out.

How does the Israelites know that Moses is a prophet of God?

There are three points:

1. The message of the promised land of Canaan;
   The message of Moses is consistent with that of the promises of God to Abraham, Isaac and Jacob. Moses confirmed (Exodus 6:8) God's promise to Abraham (Genesis 17:8), Isaac (Genesis 26:3) and Israel (Genesis 35:12) to give them the land of Canaan by leading them out of Egypt to Canaan.
   And I will give unto thee, and to thy seed after thee, the land wherein thou art a stranger, all the land of Canaan, for an everlasting possession; and I will be their God. (Genesis 17:8 KJV)
   Sojourn in this land, and I will be with thee, and will bless thee; for unto thee, and unto thy seed, I will give all these countries, and I will perform the oath which I swore unto Abraham thy father; (Genesis 26:3 KJV)
   And God said unto him, Thy name is Jacob: thy name shall not be called any more Jacob, but Israel shall be thy name: and he called his name Israel. And God said unto him, I am God Almighty: be fruitful and multiply; a nation and a company of nations shall be of thee, and kings shall come out of thy loins; And the land which I gave Abraham and Isaac, to thee I will give it, and to thy seed after thee will I give the land. (Genesis 35:10-12 KJV)
   And I will bring you in unto the land, concerning the which I did swear to give it to Abraham, to Isaac, and to Jacob; and I will give it you for a heritage: I am the LORD. (Exodus 6:8 KJV)


2. The visible Shekinah Glory of God;
   The visible Shekinah Glory of God lead the Israelites by day in a pillar of a cloud and by night in a pillar of fire. The Glory of the LORD came down and covered the Mount Sinai for six days and on the seventh day called Moses to receive the Ten Commandments.
   And the LORD went before them by day in a pillar of a cloud, to lead them the way; and by night in a pillar of fire, to give them light; to go by day and night: He took not away the pillar of the cloud by day, nor the pillar of fire by night, from before the people. (Exodus 13:21-22 KJV)
   And the glory of the LORD abode upon mount Sinai, and the cloud covered it six days: and the seventh day he called unto Moses out of the midst of the cloud. (Exodus 24:16 KJV)


3. The miracles performed in the sight of all Israel.
   The miracles performed in the sight of all Israel in the deliverance from Egypt and in the Wilderness.
   And there arose not a prophet since in Israel like unto Moses, whom the LORD knew face to face, in all the signs and the wonders, which the LORD sent him to do in the land of Egypt to Pharaoh, and to all his servants, and to all his land, and in all that mighty hand, and in all the great terror which Moses showed in the sight of all Israel. (Deuteronomy 34:10-12 KJV)

The test of a true prophet is in his message

The test of a true prophet of God lies in his message. The messages of all true prophets of God will agree with one another and can be compiled into one book, e.g. the Bible.

"If a prophet or a dreamer of dreams arises among you and gives you a sign or a wonder, and the sign or wonder that he tells you comes to pass, and if he says, 'Let us go after other gods,' which you have not known, 'and let us serve them,' you shall not listen to the words of that prophet or that dreamer of dreams. For the LORD your God is testing you, to know whether you love the LORD your God with all your heart and with all your soul. (Deuteronomy 13:1-3 ESV)

But even if we or an angel from heaven should preach to you a gospel contrary to the one we preached to you, let him be accursed. As we have said before, so now I say again: If anyone is preaching to you a gospel contrary to the one you received, let him be accursed. (Galatians 1:8-9 ESV)

Miracles do not make one a true prophet. If an angel speaks to you, it does not necessarily means that the angel is from God.

By this you know the Spirit of God: every spirit that confesses that Jesus Christ has come in the flesh is from God, and every spirit that does not confess Jesus is not from God. This is the spirit of the antichrist, which you heard was coming and now is in the world already. (1 John 4:2-3 ESV)

For many deceivers have gone out into the world, those who do not confess the coming of Jesus Christ in the flesh. Such a one is the deceiver and the antichrist. (2 John 1:7 ESV)
