For I am not ashamed of the gospel, for it is the power of God for salvation to everyone who believes, to the Jew first and also to the Greek. - Romans 1:16
1 In the beginning was the Word, and the Word was with God, and the Word was God.
2 He was in the beginning with God.
3 All things were made through him, and without him was not any thing made that was made.
4 In him was life, and the life was the light of men.
5 The light shines in the darkness, and the darkness has not overcome it.
6 There was a man sent from God, whose name was John.
7 He came as a witness, to bear witness about the light, that all might believe through him.
8 He was not the light, but came to bear witness about the light.
9 The true light, which gives light to everyone, was coming into the world.
10 He was in the world, and the world was made through him, yet the world did not know him.
11 He came to his own, and his own people did not receive him.
12 But to all who did receive him, who believed in his name, he gave the right to become children of God,
13 who were born, not of blood nor of the will of the flesh nor of the will of man, but of God.
14 And the Word became flesh and dwelt among us, and we have seen his glory, glory as of the only Son from the Father, full of grace and truth.
15 (John bore witness about him, and cried out, "This was he of whom I said, 'He who comes after me ranks before me, because he was before me.'")
16 For from his fullness we have all received, grace upon grace.
17 For the law was given through Moses; grace and truth came through Jesus Christ.
18 No one has ever seen God; the only God, who is at the Father's side, he has made him known. - John 1:1-18
16 All Scripture is breathed out by God and profitable for teaching, for reproof, for correction, and for training in righteousness,
17 that the man of God may be complete, equipped for every good work. - 2 Timothy 3:16-17
1 Paul, a servant of Christ Jesus, called to be an apostle, set apart for the gospel of God,
2 which he promised beforehand through his prophets in the holy Scriptures,
3 concerning his Son, who was descended from David according to the flesh
4 and was declared to be the Son of God in power according to the Spirit of holiness by his resurrection from the dead, Jesus Christ our Lord,
5 through whom we have received grace and apostleship to bring about the obedience of faith for the sake of his name among all the nations, - Romans 1:1-5
3 Beloved, although I was very eager to write to you about our common salvation, I found it necessary to write appealing to you to contend for the faith that was once for all delivered to the saints.
4 For certain people have crept in unnoticed who long ago were designated for this condemnation, ungodly people, who pervert the grace of our God into sensuality and deny our only Master and Lord, Jesus Christ.
5 Now I want to remind you, although you once fully knew it, that Jesus, who saved a people out of the land of Egypt, afterward destroyed those who did not believe. - Jude 1:3-5
Sola Scriptura means scripture alone.
Our Salvation is through Christ alone, shared through God's Almighty word in the form of the Scriptures.
During the Reformation, ordinary people challenged what they had been taught by Church leaders. They hungered for the truth of the Gospel. Even before this period, there were Saints who searched the Scriptures for the light. In general though, the masses were not taught the wonder that is salvation through Christ alone. They were taught to blindly follow priest and their dictates, no questions asked.
Moses brought the law which made us aware of our sin.
Please read and study your bible. The Bible is the living word of God. Do not blindly trust anyone with this gift in which God reveals Himself to you. How can you know the truth without God's revelation? Even today, many are led astray by false doctrine. There are many false religions, there are many who twist God's word and many who set themselves up as gods. The final authority in which we hope is The Lord Jesus Christ!
