Psalm 66:16 English Standard Version (ESV) Come and hear, all you who fear God, and I will tell what he has done for my soul.
Here are instructions for witnessing truth. We all want to tell about what God has done in our lives but we need to be careful. Here is the problem, He is calling us to share truth with those who already fear Him.
Proverbs 21:23-24 English Standard Version
23 Whoever keeps his mouth and his tongue keeps himself out of trouble. 24 “Scoffer” is the name of the arrogant, haughty man who acts with arrogant pride.
We must not confuse sharing the gospel with sharing truth. While there is truth in the gospel it is designed to call the lost to believe. It is the planting of the seed of faith. When we become witnesses of truth it skips all the events that the seed of faith must endure to bring about a faith that knows how to handle a word of truth.
Ecclesiastes 12:11-12 English Standard Version
11 The words of the wise are like goads, and like nails firmly fixed are the collected sayings; they are given by one Shepherd. 12 My son, beware of anything beyond these. Of making many books there is no end, and much study is a weariness of the flesh.
The lost do not have the patience for the truth.
Galatians 5:22 English Standard Version (ESV) But the fruit of the Spirit is love, joy, peace, patience, kindness, goodness, faithfulness,
The patience to handle the truth is a fruit of the spirit which can only come once the Spirit of Truth has been given. The lost do not yet have the abiding Spirit of Truth. Their arrogance proves them to be scoffers and they cannot receive the truth. If we keep our tongues we will stay out of the troubles that come with struggling with scoffers.
