What is the most important moment of your life? If you are a Christian, it is the moment you accepted Jesus Christ into your life to be your Lord and Savior. Because of your faith in Him, you now have life, and life more abundantly (John 10:10). What then is the greatest thing you can do for another person? It is to give them an opportunity to accept Jesus Christ as their Lord and Savior and experience the abundant life you now have. God has you given you both the command and the ability to tell others about Jesus Christ by the power of the Holy Spirit.
Jesus said to His disciples (us), “All authority has been given to Me in heaven and on earth. Go therefore and make disciples of all nations” (Matthew 28:19,20). We can make disciples of others by witnessing to them—by telling them about who Jesus Christ is and what He has done for us. In order to be an effective witness, you should be confident of your own salvation by faith in Jesus Christ and should be filled with the Holy Spirit. Always confess any sin you have committed to God and ask for His forgiveness, and be prepared to share your faith in Jesus. Then ask God for opportunities to witness, and talk to those whom you know and those you meet about Jesus Christ. God “desires all men to be saved and to come to the knowledge of the truth” (1 Timothy 2:4), so you can go in the power of the Holy Spirit and tell others about the salvation available through belief in Jesus Christ!
“But you shall receive power when the Holy Spirit has come upon you; and you shall be witnesses to Me in Jerusalem, and in all Judea and Samaria, and to the end of the earth” (Acts 1:8)
“And how shall they believe in Him of whom they have not heard? And how shall they hear without a preacher?” (Romans 10:14).
“And He commanded us to preach to the people, to testify that it is He who was ordained by God to be Judge of the living and the dead” (Acts 10:42).
"Preach the word; be ready in season and out of season; reprove, rebuke, exhort, with great patience and instruction." (2 Timothy 4:2)
