Jesus is the only true Way that leads to God
Christ must save, and Christ alone
God told all through the True Apostle Paul, in Ephesians 6:24,
"Grace be with all them that love our Lord Jesus Christ in sincerity. Amen."
Dear Tranquility,
Your question opens up a whole can of worms (questions) that ONLY God Our Father and Our Lord and Savior Jesus Christ Himself can teach you, little by little by personal experience.
But God, by the Grace of God, requires His True Children to get in right relationship and stay in right relationship with Him, by doing our God Priviledged Part which is that WE ourselves are truly and WHOLEHEARTEDLY forever committed to:
1 - WHOLEHEARTEDLY TRUST AND SEEK AND LOVE AND ABANDON ALL OF OURSELVES AND ALL OF OUR CONCERNS INTO God and Our Lord and Savior Jesus Christ HIMSELF, only for God and Jesus Himself, unused and untarnished by any evil self-interest, WHO TRULY DWELLS IN THE MIDST (Zephaniah 3:17) of our human spirits,
in THE TRUE HOLY OF HOLIES, WHERE God Our Father and Our Lord and Savior Jesus Christ Himself truly and forever dwells
In a nutshell...I will share some spritual Truths that God and Jesus has shown me from my own personal experiences as I have both worked with and dealt with Muslims
The Truth is that the muslim CULT just like all other cults has pieces of Truth in it, along with pieces of falsehood, or leaven (unbelief, worldliness, hypocrisy or acting) as Jesus warned about the religious of His Day, the evil leaven, especially the evil leaven of believing Deceit or false teaching, rather that God and Jesus Himself, The Only Way, Truth, Life, and Light of God
God's Own Eternally Just and Eternally True judgement...From The Beginning declares the problem, "Through DECEIT, they (the world) REFUSE to KNOW me.
And God told King Solomon, "TO KNOW THEE, LORD, IS LIFE ETERNAL
and God told The True Apostle John, "And this is the condemnation, that men LOVED darkness (their own evil selfish way) rather than Light (Jesus Himself within their human spirits) because their DEEDS or actions were evil.
In other words, men preferred their sin in this temporary mortal life, instead of WHOLEHEARTEDLY TRUSTING and SEEKING and LOVING GOD'S ONLY TRULY TRUE AND PERFECT AND MERCIFUL HOLY WAY OF SUFFERING PAIN WITH JESUS ON THE CROSS in this evil mortal life moment by moment daily until Jesus Himself returns for them.
God has shown me...tell all whether Christian, Jew, Muslim, or heathen about The Person of Jesus, Who Himself alone was
The True Faith of Abraham...and that if we (whosoever will chooses) will to simply do as Abraham did...which is to WHOLEHEARTEDLY BELIEVE AND TRUST AND SEEK AND LOVE WORSHIP JESUS HIMSELF
alone forever truly only...then God Himself, will declare them righteous ONLY IN CHRIST...NEVER OF OUR WORKS OR SELF OR SELF EFFORT...which are naturally evil due to Adam's Transgression.
and again, "Multitudes, Multitudes, in the valley of decision."
1 - The Muslims believe that 5 books are Holy:
a - The Holy Psalms of God
b - The Torah (Genesis, Exodus, Leviticus, Number, Deuteronomy)
c - All true prophets Old Testament prophets of The Lord God of Abraham
d - The Book of Abraham (which is truly a very Scriptural and Holy ancient book of God, like The Dead Sea Scrolls, but not incorporated into the other 66 Holy Scriptures of God known as The Holy Bible)
e - The Koran
the muslims are truly correct on 4 out of 5...but just like Jesus said of His own people after the flesh...so Jesus says to all..."unless you believe that I (Jesus) Am HE (THE TRUE MESSIAH) OF GOD,
you will die in your sins."
and just like any other denomination, including the Christian community, they have their share of evil false prophets or imans,
who try to use religion for their own evil self-interests to maintain power and control over others and preserve their own evil love of self...instead of doing what Jesus said all MUST DO...in they WOULD TRULY CHOOSE TO FOLLOW JESUS...which is, by The Grace of God,
DIE TO SELF, (not evilly use religion to preserve evil serpent of self),
take up their death to self, and follow Jesus, that they may Eternally Have or Possess Jesus in Holy Marriage...just for Himself...and never eternally, for any evil self-interest.
God told The True Apostle Paul, in Galatians1:8,
"But though we, or an angel from heaven, preach any other gospel unto you than that which we have preached unto you, let him be accursed."
Well...that is clear instructions that Mohammed is DEAD wrong...cuz Mohammed claimed that the angel Gabriel told him his revelations of God.
but all the false imans of islam are like using false religion to stay in power...just like the ancient evil pharisees of Jesus' time
mohammed was deceived and received DECEITFUL TEACHINGS
by satan posing as the angel Gabriel...
while Joseph Smith of mormon infamy was deceived by satan AND received DECEITFUL teachings posing as the angel moroni...
Thank God, thru Jesus Christ alone forever truly only, we see that satan has a NO POWER, game of DECEIT.
And God promised The True Apostle John that His eternally sworn enemies, the evil world would be deceived, by satan...little by little...until the time of antichrist...in the last days
"They perish because they refused to love the truth and so be saved. For this reason God sends them a powerful delusion so that they will believe the lie" 2Thess. 2:10b-11
Revelation 12:9. Because they received not the love of the truth, that they might be saved. And for this cause God shall send them strong delusion, ...
OUR ONLY HOPE, Christian, Jew, or heathen,
IS TO WHOLEHEARTEDLY TRULY AND FOREVER
1 - FULLY TRUST IN GOD AND OUR LORD AND SAVIOR JESUS CHRIST HIMSELF WITHIN OUR HUMAN SPIRITS, ALONE FOREVER TRULY ONLY, FOR OUR OWN PERSONAL (ACTS16:3031) SALVATION, (zechariah<cite> 13:9)</cite> (<cite>zephaniah3:9)</cite>PURIFICATION, AND PERFECTION (PSALMS138:8)
2 - FULLY (1PETER5:7) CASTING OR ABANDONING ALL OF OURSELVES AND EVERY THING THAT WORRIES US INTO THE TRULY MERCIFUL ARMS OF GOD AND OUR LORD AND SAVIOR JESUS CHRIST HIMSELF ALONE FOREVER TRULY ONLY, BOTH IN TIME AND IN ETERNITY
It Is Written, in Jude 1:24-25
24Now unto him that is able to keep you from falling, and to present you faultless before the presence of his glory with exceeding joy,25To the only wise God our Saviour, be glory and majesty, dominion and power, both now and ever. Amen.
