2 Timothy 3:16
All Scripture is God-breathed and is useful for teaching, rebuking, correcting and training in righteousness…
How does one become righteous? There are two answers to this question. The first is that God makes us righteous. God gives us righteousness when we have faith in Jesus Christ. This is immediate and applies to our salvation.
But there is another righteousness that takes a lifetime to achieve and it affects our relationship with God. Even though we are Christians and our salvation is secure, our sin hurts our relationship with God but He delights when we obey Him.
The Bible is our training manual. The more we study and the better we know God’s Word, the better we will follow it. Some things are automatic and others must be applied. It obviously does no good to know the difference between right and wrong if we choose to do wrong. But knowledge of the Bible can be used in our defense.
When Jesus was tempted by Satan, He didn’t stand against Him with His own power or even call upon His Father for help. Instead He used His knowledge of the scriptures to rebuke Satan and defeat temptation.
The more scripture we know, the more it is going to help us and serve as a reminder when we’re tempted by something. It is our key to living a righteous life and to pleasing the Lord.
