2 Timothy 3:16 All Scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness:
The Bible says all scripture, that is to say from Genesis to Revelation, is given by inspiration of God. This scripture (all the scripture) is profitable. We can benefit from it, gain from it, their is profit in it. There is a list given here in which one can profit in by the scripture and that is:
The scripture is profitable in doctrine. We can build our doctrine from the scripture, The scripture can teach us what God wants us to believe; not what we want to believe mind you, but what God wants us to believe. In this verse God is saying we need a doctrine. The scripture is profitable in reproof. Yes, believers need conviction and we need to be convicted of our sins. This brings into play correction. The scripture is profitable in correction. The scripture tells us what is right and what we need to do. The Bible is at a 7th grade reading level. We can read the Bible and apply it to our lives to form our life to the Bible. Example: ‘Thou shalt not kill’ Exodus 20:13 and Jesus took it deeper to be angry with someone without cause is wrong. The scripture is profitable for giving us instruction in how to live our life righteously. When we want to know what the right thing to do is, go to the scripture. The Bible often says this is right and that is wrong, regardless how we feel wrong is wrong and right is right.
The scripture teaches these things so that we can be perfect, perfect mind you in Christ, and thoroughly furnished, having the equipment needed, the knowledge needed, to do good. Unto all good works.
2 Timothy 3:17 That the man of God may be perfect, thoroughly furnished unto all good works.
