Good question. Tough though.
I grew up in a Christian home, and through repentance and faith gave my life to Christ at a young age. It was in college that I really began to question what I believe, why I believe it and how to stand on it. I studied Christian apologetics and at that time I realized that if Christ is real and the Bible is true (which has been proven to me over and over), then I need to take this all seriously and live completely for Him. He gave His life for me, He still lives and wants to show His love to me forever. And that means everything. It's not a feeling, or something mystical, but it is what I know.
A few years later I came across the Way of the Master ministries. And what I learned from them became another huge influence on how seriously I lived for Christ. Check 'em out:
[link]I love Him, His Word and want to do His will. God gave me some talents and they are to be developed and used for Him. Ephesians 2:10 reads,"For we are His workmanship, created in Christ Jesus for good works, which God prepared beforehand so that we would walk in them."
Illustrating God's Word is a good work. As well as a great many other things: loving my neighbor as myself, giving up my life for my wife, being the best dad possible, sharing the gospel, etc. But all of this starts with Him–just seeking Him. I find my life, worth and hope only in Him. Whether alone or not.
In Acts 17 Paul, when teaching the Athenians, said:
"From one man [God] made every nation of men, that they should inhabit the whole earth; and he determined the times set for them and the exact places where they should live. God did this so that men would seek him and perhaps reach out for him and find him, though he is not far from each one of us. For in him we live and move and have our being."
You are living where you are, at this time in history, with the circumstances you are experiencing in your life, so that you might reach out for Him. He is not far from you. And He is really all you need. Reach for Him with your heart. Reach out to Him in prayer. Reach out to Him in His Word, the Bible. He will reward you if you diligently seek Him (Heb. 10:6).
