All Scripture is inspired by God and profitable for teaching, for reproof, for correction, for training in righteousness; so that the man of God may be adequate, equipped for every good work. - 2 Timothy 3:16-17
To be “equipped” is to be ready, reasoned, and relational.
Scripture is the ultimate authority in all things it references. However, the truth belongs to God, and He is at work in the world, not just the church. His influence is felt on believer and unbeliever alike. Therefore we learn from many sources and are open to whatever means God uses to reveal truth. Here are stored many resources as God has shared them with us to equip anyone desiring to grow in faith and wisdom.
[May God] equip you in every good thing to do His will, working in us that which is pleasing in His sight, through Jesus Christ, to whom [be] the glory forever and ever. Amen - Hebrews 13:21
