In Matthew 10:19-20, the Lord Jesus Christ is telling His disciples what will happen to them and where they will get their strength at the time it is needed.

“But when they deliver you up, do not worry about how or what you should speak. For it will be given to you in that hour what you should speak; for it is not you who speak, but the Spirit of your Father who speaks in you.“

This is the reason we must pray without ceasing to God through the Lord Jesus Christ; the reason why we must always be in the word of God and have the Word of God in us. So many of us are afraid to share the word of God because we are not sure what to say or afraid of being asked questions we do not have the answers to or know how to answer. When we continue to pray asking God to overflow us with His Holy Spirit, we have so much strength to speak the truth in love freely without fear, without worry. At the perfect moment, the Holy Spirit will speak through us to whomever questions the word of God and whomever has uncertainty on who the Lord Jesus Christ is. The Holy Spirit uses our body to be a witness and a testimony to the world, the lost sheep of the Lord, so they can hear the gospel through our actions, and then our words.
