Your biblical responsibility to share your faith includes:
- Loving unbelievers to the extent of a reputation of being with sinners (Luke 7.34)
- Maintaining a sufficient presence among unbelievers so that you can sow the Gospel liberally by asking penetrating questions and sharing the hope in you (Luke 2.46)
- Being apologetically and spiritually prepared for questions and conversation about the Gospel (I Pet. 3.15)
- Being willing to play your role in the evangelism process (I Cor. 3.6-8)
- Asking God for open doors (Col. 4.3)
- Acts 1:8 is often used as a missions text. But it is really a “witnessing” text. It states that we, as believers, ARE witnesses. It’s up to us, by God’s grace and enabling, to be faithful or not to our identity as followers of Christ and witnesses for Him.
It is neither your ability nor your responsibility to convert people to faith in Christ. This is a sovereign work of God in a person’s life.
It should be obvious to any Christian who has read the New Testament, that all believers are responsible to witness to others about Jesus Christ and His gospel. When Jesus gave the great commission in Matthew 28:19, the command was to the whole group of disciples to go and make disciples of all the nations. “Go and make disciples”. Those eleven disciples made up what would become the church, so the command is to the whole church. Some will be goers to another country or culture, and others will be senders, but all are to share their faith, as God gives opportunity, in our own culture or in another culture. When Jesus said, “make disciples of all nations” and then “teaching them to observe everything I have commanded you”, that includes the last command to make disciples. That is, after a person becomes a disciple, then they are also to obey Matthew 28:19 and seek to make disciples, which starts with evangelism and witnessing.
These verses speak of personal responsibility to witness and share our faith:
In Acts 1:8, Jesus said, “but you shall receive power when the Holy Spirit comes upon you and you shall be My witnesses . . . “
I Peter 3:15 is a command to individual believers to always be ready to give an answer to everyone who asks you to give an account for the hope that is within you.
Colossians 4:5-6 says that we are to conduct ourselves with wisdom with outsiders, unbelievers, and have our speech seasoned with salt – speak in a tasteful and kind way so as to make people thirsty for more!
Jude 20-23 are commands for all believers, “keep yourselves in the love of God” and “save some, snatching them out of the fires (of hell), hating the sin (but loving the sinner). That is an intense description of evangelism!
Romans 1:1-7 – Paul says he was called to be an apostle, and that the church at Rome is also called, which includes a call to salvation, to sanctification, and to serve in evangelism.
In John 9, the man that was born blind is a good model of giving our testimony when we don’t know the answer to some questions. “all I know is that I was once blind, but now I see”.
2 Corinthians 5:11-21 is also about how the fear of the Lord gripped the apostle the Paul to seek to persuade people about Christ and how the love of Christ controlled him to live for the Lord. We should also.
