So be careful how you live, not as fools but as those who are wise. Make the most of every opportunity for doing good in these evil days. Don’t act thoughtlessly, but try to understand what the Lord wants you to do. Don’t be drunk with wine, because that will ruin your life. Instead, let the Holy Spirit fill and control you. Then you will sing psalms and hymns and spiritual songs among yourselves, making music to the Lord in your hearts. And you will always give thanks for everything to God the Father in the name of our Lord Jesus Christ.
And further, you will submit to one another out of reverence for Christ.
Ephesians 5:15-21

How do I know Christianity is true? Another source of confirmation comes from the person of Jesus Christ. Among all men who ever lived, Jesus stands apart from each one. Throughout the gospels, Jesus claimed Himself to be God. He claimed to have authority over the law, creation, sin, and death. John 10:30-33 states,

'I and the Father are one.' Again the Jews picked up stones to stone Him but Jesus said to them, 'I have shown you many great miracles from the Father. For which of these do you stone me?' The leaders replied, 'We are not stoning you for any of these but for blasphemy because you a mere man, claim to be God.'

The Jewish enemies of Christ clearly understood His claims and it is for this reason they killed Him. His disciples also understood His claim and presented it in their message. Not only did He make an extraordinary claim; Jesus confirmed it. There are numerous ways in which Christ proved His claims. I will cover only four.

The first confirmation of Jesus' claims is His sinless life. Jesus' most intimate companions stated He committed no sin that He needed to repent of. Paul writes of Christ, "God made Him who had no sin to be sin for us, so that in him we might become the righteousness of God." (2 Cor. 5:21) It would have been hypocritical of Jesus if He had indeed sinned and never repented, for He taught all men this principle. Even His enemies could find no sin in Him. Pontius Pilate, after examining Jesus, stated to the angry mob, "I find no basis for a charge against him." The Bible declares God is holy and Jesus showed Himself to be holy as well.

The second confirmation is the impact of Christ on mankind. More schools and colleges have been built in the name of Christ than any other man. More hospitals and orphanages are built in the name of Christ than any other person. More literature and music are written about Christ than any other person. More laws and ethical codes are built on His teachings than any other man. He has had a tremendous impact on every area of culture like no one else.

The third confirmation is the miracles He performed. God's existence makes it reasonable to assume He would use miracles to confirm His message and messenger. Miracles are a powerful confirmation because it authenticates the creator's authority over His creation. Christ's miracles over nature, sickness, spiritual forces, sin, and death displayed this authority over every realm of creation.

The fourth confirmation is the fulfilled prophecies. Before He set foot on the earth, there were over seventy specific prophecies made by the Old Testament writers about the Messiah. The prophecies included the city of birth, His method of execution, His betrayal, the date of His death, etc. Jesus fulfilled each of these. The probability of His fulfilling just eight of these by chance is very close to a mathematical zero.

No one has both made the claims of Christ and confirmed them, as He did. His life is another proof Christianity is true.{5}
