Evangelism is difficult because unbelievers do not want to be evangelized. They do not want to believe our gospel message and so they suppress the truth in unrighteousness being dead in their trespasses and sins.

Becoming a Christian is difficult. In fact it is impossible for us to turn ourselves into Christians. Only God can do it. Living the Christian life is difficult, because pockets of resistance to God still remain within us, which we call indwelling sin.

So then where do we find the power to become Christians, to live like Christians, and to make our witness effective in the hearts and lives of those who are still lost in their unbelief? In Acts 1:8 Jesus promises us such power: ...but you shall receive power when the Holy Spirit has come upon you; and you shall be My witnesses both in Jerusalem, and in all Judea and Samaria, and even to the remotest part of the earth.
