You are called to serve God. Regardless of your job or career, you are called to full-time Christian service.
We are not just Christians on Sunday morning, but all the time. Take an extra measure of time to think about your actions today. Are you offering part-time or full-time service to the Lord?
For those God foreknew he also predestined to be conformed to the likeness of his Son, that he might be the firstborn among many brothers. And those he predestined, he also called; those he called, he also justified; those he justified, he also glorified.
