“I have found that the main thing that keeps me in-line is the fear of God.”
This statement of yours gives me concern. I will say in honesty that the main thing that keeps me in-line is the love of God. I am so grateful for His mercy and salvation.
“For God hath not given us the spirit of fear; but of power, and of love, and of a sound mind.” 2 Timothy 1:7
We are at times admonished to fear God; but still more to love God. What is the first and greatest commandment? To love the LORD our God with all our heart.
It is love that was God’s motivation to give His son, love for His people that drove Jesus to the cross; love, not fear.
“We love Him because He first loved us.” 1st John 4:19
Christians don't "follow" the law, they live its precepts, not always in a perfect fashion, and his ever present Grace is there when we fail.
