It's in Christ that we find out who we are and what we are living for. Long before we first heard of Christ and got our hopes up, he had his eye on us, had designs on us for glorious living, part of the overall purpose he is working out in everything and everyone. Ephesians 1:11-12 (MSG)
"The word secular isn't in the Bible. It all matters to God; everything in your life is important to God."
Many Christians don't make the connection between Sunday and Monday. They compartmentalize their lives. They think, Well, I've got a spiritual life and I've got a secular life. My spiritual life is when I read the Bible, when I pray, when I go to church, I do good things for others. That's my spiritual life.
And that's over in one compartment. So then, they think, over in another compartment: This is my secular life. That's my work, my job, my career, my business decisions, my finances, my pension plan; all these things are my secular life.
God says, "No, that's wrong. All of life is spiritual."
The word secular isn't in the Bible. It all matters to God; everything in your life is important to God. God is as interested in your work as He is in your prayers. In fact, I would suggest that He is might be more interested in your job because you spend more time working than you do praying.
The fact is, your relationship to Christ is like marriage. Marriage is a full-time relationship, and so is your relationship with Christ. What do you think would happen if I came up to my wife and said, "Honey, I'm going to only act married when I'm at home."
The fact is, all of life is important to God, and you can't separate your Christianity from your work -- just as you can't separate your Christianity from your life.
