“But godliness with contentment is great gain.” - 1 Timothy 6:6 (KJV)
A life of godliness will lead to a life of contentment. Being content with what we have and where we are in life is not easy. Society and our natural tendencies drive us to never be satisfied. Our sinful nature is one of greed. We want, we want, and we want some more. No person can truly be content through their own strength. This can only come from the power of the Holy Spirit.
When you live outside of God’s will; you will never be content. You won’t be experiencing the best for your life. You won’t be where Christ wants you to be. But, when you are walking where the Lord wants you to be contentment is inevitable. God will satisfy you. You will understand that He is working your entire life out in His own perfect timing. A life of godliness will lead to contentment which will lead to a great gain for your spiritual growth. Trust Jesus.
