"Plans fail for lack of counsel, but with many advisers they succeed" (Proverbs 15:22).
Confirming major decisions through the counsel of others is one way God protects us from poor decisions. This process is designed to confirm direction for which we are seeking confirmation. Paul was sensitive not to get too heavy-handed in the confirmation process though. He offered advice to others but was not the enforcer of their decisions. "And here is my advice about what is best for you in this matter" (2 Corinthians 8:10).
The requirement for efficient administration frequently requires single points of decision-making. Where there is willingness and trust to receive input, there is also humility, faith, and grace for God to work His pleasure in His servant. Where there is unwillingness, the opposite is true.
There have been times in my life where I have felt strongly about a certain issue only to receive feedback from those close to me which revealed that I was not accurate in my assessment of the situation. I have learned to yield in such situations, trusting that God is working through those in whom I am accountable.
The scriptures encourage us to seek advice and counsel from other Godly people who share the same values and goals that we have. "Listen to advice and accept instruction, and in the end you will be wise" (Proverbs 19:20). "Make plans by seeking advice; if you wage war, obtain guidance" (Proverbs 20:18).
Peace of mind is another important confirmation requirement for making decisions. If you do not have peace about a decision, you should wait until God gives you peace. This does not mean your decision may not have some tension due to the faith aspect of it, but deep down you should have a peace that it is the right decision. "Do not be anxious about anything, but in everything, by prayer and petition, with thanksgiving, present your requests to God. And the peace of God, which transcends all understanding, will guard your hearts and your minds in Christ Jesus" (Philippians 4:6-7).
Do you need to make a major decision? Ask God to give you confirmation through others.
