Witnessing
Many have accepted Christ by watching Christians more than talking. In 1 Corinthians 13:5 says "Love does not act unbecomingly"; which means a Christian should demonstrate godly love and have real credibility. Your credibility is evangelism.
I know Christianity is Right and Real because Jesus gave a wonderful example that HE is the way and the truth and the life. No one comes to the Father except through HIM. (See John 14:6). During Jesus' ministry, Jesus spoke of His coming death. "Destroy this temple," Jesus said, referring to His body, "and I will raise it again in three days." Jesus also declared that the Father would raise Him up on the third day. In Romans 1 we read that the Spirit of God declared Jesus to be the Son of God with power "by his resurrection from the dead." Hebrews 9:14 tells us that Father, Son and Holy Spirit all had a part. The Father received the offering of the Son through the Holy Spirit. Jesus Christ, who is God, the blameless and sinless Son, offered as the Lamb of God, without spot and without blemish. The redemptive price was paid by the Son to the Father through the Spirit.
Christ is more than a system, tradition, or belief. He is a Person who knows our needs, feels our pain, and sympathizes with our weakness. In exchange for our trust, He offers to forgive our sins, to intercede for us, and to bring us to His Father. He cried for us, died for us, and rose from the dead to show that He was all He claimed to be. Conquering death, He showed us that He can save us from our sins, live His life through us on earth, and then bring us safely to heaven. He offers Himself as a gift to anyone who will trust Him (John 20:24-31).
