Scripture informs us of two different, diametrically opposed kinds of happiness. One springs forth from engaging in fruits of the Holy Spirit (Galatians 5:22), whereas the latter comes from partaking in fleshly desires (Hebrews 11:25). Allowing sin to have dominion over our lives is futile, and dangerous to the soul (Galatians 6:7-9). It is unprofitable for us. Fulfilling sinful lusts can only result in feeling finite, temporary satisfaction. In other words, surrendering our will to sin can only result in us feeling a self-deceptive perversion of happiness. Sin is defined scripturally to mean the breaking of God's commandments (1 John 3:4). It is a failure to live up to reality. It is a failure to appreciate the good things that God has designed for us. A sin addiction necessarily involves a repetitive cycle of engaging in that specific transgression. It is pointless to continue in that lifestyle because it can never satisfy the longings of the human soul. That is selfishness and idolatry. We cannot resort to a finite source to quench a longing that demands infinite fulfillment. We cannot have lasting happiness and fulfillment apart from God. It is only through Him that we even consistently adhere to objective moral laws. It is only through Him that we can have peace and order. Joy is not a byproduct of holiness, but rather is holiness itself (Psalm 1:1-3; Matthew 5:2-12). It can only be found in serving God according on His terms.
God is the ultimate source of our happiness. Not everything that happens in life will bring us into that state of being, but God leads people of faith to true and abiding happiness. It is centered around the Person and work of Jesus Christ. We are set free from sin through the transforming power of the Holy Spirit. God is worthy of our dedication. Our joyous state should therefore be a positive reflection of our spiritual health. We should be striving to be holy as God Himself is holy. Godliness is exemplified in thought, word, and deed. This is true happiness. The world is not our eternal dwelling place, and so we should not strive to live like its people. Sin can never result in happiness or fulfillment. It is not a psychological but supernatural bliss He gives to those who love Him. It will not be fully brought to realization until we enter the eternal state. Our hearts need to be made right with God in order to experience this kind of bliss.
