2 Peter 3:1 Dear friends, this is now my second letter to you. I have written both of them as reminders to stimulate you to wholesome thinking.
We must not forget that our bibles are actually written by human hands and that some of them are letters written by people to other people as words of encouragement and guidance.
Because they are so important they have been included in what we call our bibles because the people that wrote them were guided by God to write them. God wants us to think along His lines and not to be swayed by worldly ways.
Reading our bibles will help us to remember His ways and help us to think more along His lines that of worldly ways where we could quite easily get lost in our own devices.
