Every believer battling temptation faces an inward struggle. A part of him (his spirit) wants to do right and to please the Lord, while another part of him (his flesh) loves sin and self more than the Saviour. If this struggle goes unchecked, the flesh will certainly win every time. Man’s spirit requires reinforcements in order to win this battle. According to Matthew 26:41, two of these resources include watchfulness and prayer. It is imperative for each believer to implement both, for one without the other leaves a person with certain vulnerabilities when temptations arise. Watchfulness demonstrates the saint’s personal responsibility, while prayer demonstrates his need for God’s intervention.
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.
