Why is Prayer integral?
Without [prayer] your witness will be far less effective and you will be far more vulnerable to the enemy. When you witness, you need the blessing and support of the Lord. You need to be in fellowship with Him. Prayer makes this all possible.
What should you pray for?
When you witness you plant the seeds of the Gospel, but it is God who causes the growth (1 Cor. 3:6-7). In prayer you ask God to give that growth. In prayer you ask God to convict the unrepentant of their sin and by that awaken in them the need for salvation. In prayer you, "...let your requests be made known to God," (Phil. 4:6).

Jesus wants people to find salvation and enjoy eternal fellowship with Him. He wants you to preach the Gospel. He has given the command "Go therefore and make disciples of all the nations..." (Matt. 28:19). Your witness for God may or may not be verbal. But either way, you need to pray and ask God to give you strength, love, and insight.
Pray for compassion for the lost. Compassion is a necessary element in witnessing. It motivates you to speak, to teach, and to pray for others to come into the kingdom of God. Compassion helps you to cry over the lost and to come to God in humble request for their salvation. Paul said, "Brethren, my heart's desire and my prayer to God for them is for their salvation," (Rom. 10:1).
Pray for the desire to witness. Pray this regularly and watch the Lord change you and give you a desire to reach out and tell people about Jesus. God will grant your prayers and joy will fill your heart as you fulfill the command of God by witnessing.
Pray for boldness. Pray for the courage to step out in faith and speak up when needed. Many Christians are timid because speaking a word for the sake of the Lord can be risky and frightening. Boldness gives you the courage to risk ridicule and to endure the scorn. Ask God for it. "For God has not given us a spirit of timidity, but of power and love and discipline. Therefore do not be ashamed of the testimony of our Lord," (2 Tim. 1:7-8).
Pray to the Lord to bind Satan and his angels. There is a hierarchy of demons seeking to hinder your witness and steal the seeds of the Gospel that you plant. You cannot fight spirits with reason or flesh and blood, but you can ask the Lord to fight. With prayer you can assault the camp of the enemy and weaken his false kingdom. Prayer is a mighty tool, a powerful tool. You need it if you are going to witness.
Pray for your needs. Do you have a close walk with God? Do you need a deeper fellowship with Him? Do you have sins you need to confess and forsake? If so, then pray. Enjoy your privilege of coming to the Creator of the universe who meets your every need. He loves you. He wants to hear from you and He wants you to make your needs known to Him. "Be anxious for nothing, but in everything by prayer and supplication with thanksgiving let your requests be made known to God," (Phil. 4:6).
