Our destiny is to love and honor God for it is what we were created for. If we dont accept that destiny then life on earth will be hell no matter how we try to be happy.
I will accept that point.
But must counter also, with the thoughts of Ecclesiastes, Psalms, and Proverbs:
that the evil prosper, and the righteous suffer.
The Peace of God is not merely "inner peace", but is "out-of-this-world" peace. Inner peace can be attained by ANY human. The Peace of God can only be obtained by the elect, through the Spirit.
The selfish and greedy will generally be "successful" by worldly standards. That is what all the Self-Help books are all about.
Life on earth matters little, in the light of eternity. Many believers face "hell on earth", just as unbelievers do.
Jesus is not a means to living well on earth. Jesus is a means to eternal life.
Many who gain eternal life of heaven must first pass through all the hell that earth has to offer.
Let us not deceive ourselves or others. The blessings and promises of God do not guarantee any worldly success, happiness, longevity, or comforts.
Satan promises those things.
