Witness effectively for the kingdom of God as is instructed and commanded by the Lord through the Bible. Apply it wherever you go and in everything you do throughout your life as you serve Him.
This is the Great Commission, as was given to all believers who love and want to follow the Lord. His purpose should and must become your purpose as you look to see what it is He wills you to do in your life.
Observe here, how it has been commanded to us in Matthew 28:18-20, where it says, "And Jesus came and spake unto them, saying, 'All power is given unto Me in heaven and in earth. Go ye therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost: Teaching them to observe all things whatsoever I have commanded you: and, lo, I am with you always, even unto the end of the world. Amen.'" Wow! What a promise!
You may have a bit of fear or shame in sharing the gospel of Christ with other people. We all do from time to time as we grow in our faith; but you need not let that hinder you. Of course, Satan would love it if it you allow fear to overtake you, or if you felt embarrassed or shameful in telling others how Jesus changed your life.
I too have felt that way and have felt a bit of shame and fear in sharing my Christian testimony with others; however, one day I heard a powerful sermon from a gospel preacher, who preached on the love of Christ and how to be a witness for Him, and in it, he quoted these verses:
Through the word of God, the Lord will reveal these truths to you as you contemplate what your testimony and witness to others really means. Jesus honors you when you honor Him as you share the Good News to those who don't know Him, in proclaiming His name.
Telling others about Jesus requires you and me to speak out for Him boldly without any fear, shame, or trepidation. It includes those times when you see that His name is being blasphemed, or when He is being mocked by those who do not know Him, or just in standing up boldly for His sake where there is evil present, or worldly and sinful acts and behaviors going on; such as in the cases of abortion, homosexuality, murder, gossip, using profanities, and various other sins you may see within society or within your own workplace and neighborhood. You will have many opportunities to speak out and to contend for the faith.
There will always be a time when you can witness and speak up for Christ, but when you do, make sure you are speaking in biblical truth, and not in error. This is one of the reasons it is so important to know and understand your Bible. Memorizing scripture and text is always a great help when you want to share your faith with those who are living in sin. The Holy Spirit will come to your aid as you share and witness for the gospel of Christ. It says so in these passages of scripture:
Basically, your Christian witness and testimony is where you reveal to others (1) what has already been witnessed (seen, heard, and experienced) by those people in Biblical times through Jesus' disciples, prophets, and others who saw, believed, and testified of Him to others, and (2) through the witness of your own life, benefiting from the change and transformation of which God has placed inside of you, thereby giving you an effective means of courage in reaching others for Christ.
Telling others about Christ can be a bit scary or daunting in the beginning because you are not sure how people will accept you or your message. Just remember though, we are commanded by God to go, such as was told in:
We are also to reach out to others in love, just as Jesus did throughout all His time on earth before His descension into Heaven. Look at these verses to understand His perfect example:
In essence, being a sole-winner for Christ brings joy to the believer's heart; furthermore, it pleases God so much in that you honor and obey Him through your life and your effectiveness as a Christian witness for Him.
You can see how it pleases the Lord as it says in Proverbs 11:30, stating that, "The fruit of the righteous is a tree of life; and he that winneth souls is wise." Here you know you are doing His will when you point others to Christ.
Matthew 9:37-38 demonstrates the sadness in the heart of Jesus after having such compassion on the multitudes of people all around Him. Here He laments, "Then He said unto His disciples, 'The harvest truly is plenteous, but the laborers are few; Pray ye therefore the Lord of the harvest, that He will send forth laborers into His harvest."
I love how Paul gives us the needful hope and courage in this labor for Christ when he said in 2 Corinthians 2:14, "Now thanks be unto God, which always causes us to triumph in Christ, and maketh manifest the savour of His knowledge by us in every place." What encouragement!
Finally, I would like to encourage you as well; to go out today, and tell. Tell those who do not know; how the Savior Jesus Christ came to seek and to save those who are lost; how He saved you and changed and transformed your life; and how He can and will change their lives too.
May God bless you as you continue to point others to Christ, and in being a faithful witness for Him.
