The Bible says contentment is being satisfied because God is working everything together for my good and for his glory. Philippians 4:13, I Timothy 6:6
Yet, we often struggle with being content. Our minds continually manufacture reasons not to be content. In response the Holy Spirit says:
The Lord is my shepherd, I lack nothing. Psalm 23:1
So this issue of contentment cannot be resolved by evaluating your circumstances. It is resolved by evaluating what you believe.
