Maybe you have been skeptical about the claims of Christianity. You have thought that the glorious hope of the Christian is just built on wishful thinking. But now, try to be fair, for the time being, to shelve whatever objections you may have until you have carefully and fairly considered the positive evidence.
It is certain that the universe as we know it must have had a definite beginning. The older philosophies of the eternity of matter have been set aside by modern physics and astronomy. Some compare the universe to a clock that is running down. The Second Law of Thermodynamics states that every energy change or transfer must be in a downward direction, as far as the usability of energy is concerned. Our sun and stars continually send out tremendous quantities of energy, most of which is lost in space. Obviously, this cannot go on forever. "And, Thou Lord, in the beginning hast laid the foundation of the earth; and the heavens are the works of thine hands: They shall perish, but thou remainest; and they shall wax old as doth a garment; And as a vesture shalt thou fold them up, and they shall be changed: but thou art the same, and thy years shall not fail" (Hebrews 1:10-12)(KJV).
If the law of cause and effect means anything, the universe could only have been brought into existence by a cause adequate to account for everything, every concept, every character exhibited by the universe. It is axiomatic, at least as far as anything now going on in the universe is concerned, that the effect cannot be greater than the cause. Therefore, the only reasonable conclusion, if the law of cause and effect means anything, is that the universe and everything in it was created by a great personality, a Person we call God.
In science or technology, the accuracy of the theory or a hypothesis is necessarily subject to doubt until put to a experimental test. It must be recognized that in Christianity as well, the ultimate demonstration of its truth awaits the return of Jesus Christ. In the meantime, however, it is empirically proven, millions of times over, that reception of Christ into the heart of the individual, by faith, transforms that individual into a new creature. "Therefore if any man be in Christ, he is a new creature, old things are passed away, behold, all things are become new" (2 Corinthians 5:17).
It is sadly true that not all professing Christians give any such evidence of a transformed life. Many consider themselves Christian on the basis of church membership, baptism, sacraments or more or less Christian ethical standards. But true Christians with absolute honesty and sincerity, testify that a change in nature and purpose resulted from their decision to believe in Christ Jesus as the eternal Son of God and their personal Saviour. Amen!
