Acts 4:31, And when they had prayed, the place where they had gathered together was shaken, and they were all filled with the Holy Spirit and began to speak the word of God with boldness. Webster Definition of Boldness is a willingness to take risks and act innovatively; confidence or courage. Showing or requiring a fearless daring spirit. The Prerequisite for being a bold witness for Christ is to have confidence in the word of God and the Power of the Holy Spirit. Knowing this is your confidence in Him, which will empower you to be a “bold” witness for the Kingdom of God! Confidence is define as to have an inward certainty, to be convinced, a trust.  An assurance that stands firm upon a foundation that has substance and or boldness. Proverbs 3:26 says, for the Lord will be your confidence and will keep your foot from being caught and 1 John 5:14 “Now this is the confidence that we have in Him, that if we ask anything according to His will he hears us”. It’s through confidence in our Helper, the Holy Spirit that when we come into contact with someone, He will give us the words we need to speak, “Settle it therefore in your hearts, not to meditate before what ye shall answer for I (Christ) will give you a mouth and wisdom, which all your adversaries shall not be able to gainsay nor resist”(Luke 21:14-15) And In Psalms 118:8 it says, “It is better to trust in the Lord than to put confidence in man”, man includes the fleshly part of you.  This is how we overcome the fear of failure by trusting in the Lord with all thy heart and leaning not unto thy own understanding, but in all thy ways acknowledging Him and He will direct thy paths (Proverbs 3:5-6). We must remember that the Holy Spirit is on the inside of us. He is our helper. Call upon him to help you say the right things; he already knows what you are thinking.  Remember, the person may not receive salvation the moment you share the Word with them, have a farmer’s mentality like Paul.  He said in the book of 1 Corinthians 3:6, “I have planted, Apollos watered; but God gave the increase”.  So confidence in Jesus and the Word must always outweigh what we feel.  You may feel like you didn’t get through to that individual, but God has a plan and our confidence must be in God’s plan concerning that person’s life. One of the ways you can walk in confidence it to start by knowing who you are in Christ Jesus.  A good example is David.  While visiting his brothers and the Israelite soldiers on the battlefield, David listened as Goliath, the Philistine giant demanded an opponent for battle.  It was then that David asked an important question in 1 Samuel 17:26, he asked, “for who is this uncircumcised Philistine, that he should defy the armies of the living God”?  Basically, David was saying, look we are the promised people of the living God.  How can this guy think he could defeat the people who are in covenant with the Almighty God?  So walking in confidence means you must know what God says about you.  Know the promises of God and trust in them.  Later David asked permission of King Saul to challenge Goliath.  The king himself doubted that David could defeat the giant.  But David explained in 1 Samuel 17:36-37 “that the Lord had delivered him out of the paw of the lion and the bear and that God would deliver him out of the hand of this Philistine”.  This shows the inward certainty that David had in God.  Confidence to overcome feelings, emotions and bad thoughts can be defeated by remembering other trials and tribulations God has brought you through.  He is the same yesterday, today, and forevermore. Remember God is the one in control. All we need do is yield to His leading and He will direct our steps.  For in Him we live, and move, and have our being.  (Acts 17:28, Galatians 1:16). The Greek word translated “boldness” means “outspokenness, frankness, plainness.” That word expresses the idea of “courage, confidence, and fearlessness.” Boldness does not mean bluntness, arrogant, or rudeness. It’s knowing who you are in Christ and His Power and Ability operating in you to move and speak boldly. While being bold, we also want to be peaceable with all. (Rom. 12:18) Also, as we minister the good news of God’s Kingdom know the difference between boldness and tactfulness (be considered and courtesy) so that you do not offend someone intentionally. This type of boldness does not come from within or from self-reliance. But this Holy Boldness comes from the Creator Himself as a result of us being rooted and grounded in the Word and filled with the Spirit of God. Matthew 10:20, “For it is not you who speak, but it is the Spirit of your Father who speaks in you.  And because of the faith and hope we have in Christ Jesus We’re able to speak the word with boldness. 2 Corinthians 3:12
