Keep a song in your heart.
The consequence of sin is death. It's in the Bible, Romans 6:23, NIV. "For the wages of sin is death, but the gift of God is eternal life in Christ Jesus our Lord."
Men reap the consequences for their actions. It's in the Bible, Galatians 6:7-8, TLB. "Don't be misled; remember that you can't ignore God and get away with it: a man will always reap just the kind of crop he sows! If he sows to please his own wrong desires, he will be planting seeds of evil and he will surely reap a harvest of spiritual decay and death; but if he plants the good things of the Spirit, he will reap the everlasting life which the Holy Spirit gives him."
You will be treated in the same way you treat others. It's in the Bible, Matthew 7:1-2, TLB. "Don't criticize, and then you won't be criticized. For others will treat you as you treat them."
