Every unsaved person will have windows of opportunities when he becomes most receptive to the gospel of Christ. The Devil works hard to keep people in darkness and will distract them by every means necessary (i.e., the death of a loved one, a crying child, a ringing phone, busyness, etc.). The salvation of a soul involves a spiritual battle that can only be won by the Lord’s intervention. There is a window of time when the lost are most receptive to the gospel, likewise suggesting only a window of opportunity for the saved to speak for Christ. This is the very reason the apostle Paul stressed the importance of the saints of God beseeching the Lord to open to them a door of utterance (Ephesians 6:19).
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.
The believer is to allow no place for bitterness within his life. The book of Ephesians directly associates bitterness with the sins of wrath, anger, clamour, evil speaking, and malice. Each of these sins grieves the Spirit of God and ought to grieve the believer. As such, Christians are admonished to put away all bitterness. As bitterness shows itself in the depths of our hearts, we ought to immediately seek the Lord and plead for His help in removing it by its root. In a similar passage (Colossians 3:8), we are admonished to “put off” many of these other sins mentioned. Always keep in mind that bitterness does not edify the believer or those around him, nor does it glorify the Lord. Simply choose to obey God by putting away and putting off bitterness.
