Sola Scriptura
The Bible didn't originate with man. Rather, it originated with God and the Holy Spirit. It was God giving us his grand, redemptive, plan of humanity! God is a loving God who wants us to know him. When was the last time you let God's word read you? When we spend time in the word, it reveals our intentions, our wrongs, and the things we're doing right. Scripture cuts to the heart, reveals our need for righteousness, and points us to the righteous one. We must devote ourselves to the teachings of God's word. The Bible alone is the sole authority on how we should live our lives.
"All Scripture is inspired by God and is useful to teach us what is true and to make us realize what is wrong in our lives. It corrects us when we are wrong and teaches us to do what is right." 2 Timothy 3:16
