1 Samuel 23:1-5 NLT One day news came to David that the Philistines were at Keilah stealing grain from the threshing floors. David asked the Lord, “Should I go and attack them?” “Yes, go and save Keilah,” the Lord told him. But David’s men said, “We’re afraid even here in Judah. We certainly don’t want to go to Keilah to fight the whole Philistine army!” So David asked the Lord again, and again the Lord replied, “Go down to Keilah, for I will help you conquer the Philistines.” So David and his men went to Keilah. They slaughtered the Philistines and took all their livestock and rescued the people of Keilah.
In the above referenced passage of scripture, David asked the Lord a specific question and received a specific answer. The interesting thing is that even after David received confirmation from the Lord, the fear of his mean caused David to question the Lord and ask him the same question again. He asked in a "Are you sure, Lord?" kind of way.
I think it is wise to seek Godly counsel but I don't think that we should allow the fear and doubt of those around us to question what we already know to be true or question what God has already confirmed for us. This is why it is so important to seek the Lord for yourself! Seek the Lord above all things and He will certainly direct your path but you must trust Him and walk in faith.
When those around you are causing you to question the direction that God is leading you in, continue to stand firm in God's Word. Remain steadfast and unwavering. Do not be a double-minded person.
May the Lord continue to lift you by His power, encourage you to stand strong in faith and equip you to walk along the path that He has predestined for you!
