Talks about the tongue being very important. V5- The tongue can be a spark to start a fire. The tongue reveals the heart.
You brood of vipers, how can you who are evil say anything good? For out of the overflow of the heart the mouth speaks. – Matthew 12:34
Can both fresh water and salt water flow from the same spring? (v11)
Put off: earthly wisdom, which exhibits bitter envy, selfish ambition (v14)–> boasting (v15), disorder, evil practice (v16)
Put on: Godly wisdom, which is first of all pure; then peaceloving, considerate, submissive, full of mercy and good fruit, impartial and sincere. Peacemakers who sow in peace raise a harvest of righteousness. (v17-18)
The unity and peace within the body of Christ has God’s glory at stake! We should not be hypocritical and “prase our Lord and Father” and “curse men, who have been made in GOd’s likeness” at the same time.
