Only One Way

All have sinned.
Indeed, there is not a righteous man on earth who continually does good and who never sins. (Ecclesiastes 7:20 NASB)
For all have sinned, and come short of the glory of God; (Romans 3:23 KJV)

But God is merciful.
Have I any pleasure in the death of the wicked, declares the Lord GOD, and not rather that he should turn from his way and live? (Ezekiel 18:23 ESV)

But God is also just and will by no means leave the guilty unpunished.
The LORD is slow to anger and great in power, And the LORD will by no means leave the guilty unpunished. In whirlwind and storm is His way, And clouds are the dust beneath His feet. (Nahum 1:3 NASB)
Then the LORD passed by in front of him and proclaimed, "The LORD, the LORD God, compassionate and gracious, slow to anger, and abounding in lovingkindness and truth; who keeps lovingkindness for thousands, who forgives iniquity, transgression and sin; yet He will by no means leave the guilty unpunished, visiting the iniquity of fathers on the children and on the grandchildren to the third and fourth generations." (Exodus 34:6-7 NASB)

In demonstration of His love and in order to reconcile mercy and justice, God sent His only begotten Son Jesus to die for our sins.
But God demonstrates His own love toward us, in that while we were yet sinners, Christ died for us. (Romans 5:8 NASB)
For our sake he made him to be sin who knew no sin, so that in him we might become the righteousness of God. (2 Corinthians 5:21 ESV)

That whosoever who believes in Him will be saved.
For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life. (John 3:16 KJV)

Those who believes not will be condemned.
Whoever believes and is baptized will be saved, but whoever does not believe will be condemned. (Mark 16:16 ESV)
Whoever believes in him is not condemned, but whoever does not believe is condemned already, because he has not believed in the name of the only Son of God. (John 3:18 ESV)
Whoever believes in the Son has eternal life; whoever does not obey the Son shall not see life, but the wrath of God remains on him. (John 3:36 ESV)
If anyone hears my words and does not keep them, I do not judge him; for I did not come to judge the world but to save the world. The one who rejects me and does not receive my words has a judge; the word that I have spoken will judge him on the last day. (John 12:47-48 ESV)

For he has (1) trampled on the Son of God, (2) regarded as profane the blood of the covenant by which he was sanctified, and (3) insulted the Spirit of grace.
Anyone who has set aside the law of Moses dies without mercy on the evidence of two or three witnesses. How much worse punishment, do you think, will be deserved by the one who has trampled underfoot the Son of God, and has profaned the blood of the covenant by which he was sanctified, and has outraged the Spirit of grace? For we know him who said, "Vengeance is mine; I will repay." And again, "The Lord will judge his people." It is a fearful thing to fall into the hands of the living God. (Hebrews 10:28-31 ESV)

There is only one way.
"And there is salvation in no one else; for there is no other name under heaven that has been given among men by which we must be saved." (Acts 4:12 NASB)
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 KJV)
