Everything that was written in the past was written to teach us. Those things were written so that we could have hope. That hope comes from the patience and strength that the Scriptures give us.
The things that happened to those people are examples. And those things were written to be warnings for us. We live in the time that all those past histories were pointing to.
When we pray to God our Father we always thank him for the things you have done because of your faith. And we thank him for the work you have done because of your love. And we thank him that you continue to be strong because of your hope in our Lord Jesus Christ.
So prepare your minds for service, and have self-control. All your hope should be for the gift of grace (kindness) that will be yours when Jesus Christ appears (comes).
