The Bible says that “out of the abundance of the heart the mouth speaketh” (Matthew 12:34). This means that the words proceeding out of our mouths originate in our hearts. When we speak bitter words, it is because there is bitterness within our hearts. David likened bitter words to arrows that pierce the flesh (Psalm 64:3). Our words ought to be “seasoned with salt” (Colossians 4:6); instead, we often allow our words to pierce through others. We tear people down rather than building them up. Why is this? Because we have a root of bitterness growing inside that finds its way from our hearts into and out of our mouths. Those who demean others generally do so because they are bitter. Attempts to justify this behaviour are fruitless because the Lord knows the root of the problem stems from our heart.
Since God is responsible for man’s possessions or the lack thereof, some Christians question why God gives a man some things while He withholds from others. Romans 8:28 contains one of the answers as it points out that “all things work together for good.” This does not imply that everything in the believer’s life is enjoyable or good. It means that everything combined results in good. God works in every piece of a believer’s life. He combines all things so that even the supposed bad things result in what is “good” according to the will of God. So long as God is at the controls, contentment teaches man how to be satisfied. Man's conditions, circumstances, and possessions are appropriate because God has worked everything together for the good of that man.
