Reality does not consist only of that which we can see, hear, taste, smell, or feel physically. There is another world--a spiritual world that we can only see by faith. But it is there and it is really more real than what we can experience with our five senses. Everyone has a little inkling of this world(which we will call, "eternity"). Ecclesiastes 3:11 says that God has placed eternity in our hearts. We all have a sense that there is more to this world. One of the great proofs of the existence of the God of the Bible is that almost every society values things that one cannot see, hear, taste, smell, or touch. Qualities such as love, joy, peace, kindness, goodness, patience and godliness are admired and sought after by people from every generation and nation. We know them to be God-like qualities that come to us as fruit of the Spirit.
One day the disciples were walking in the Temple area with Jesus and pointing out the magnificent buildings. Jesus said, "Yes look at these great buildings. But they will be completely demolished. Not one stone will be left on top of another."(Mark 13:2) One day all of humankind's accomplishments will be gone. Only what
is spiritual will remain. Our world is temporary. God's kingdom is forever.
In Jesus, Eternity entered into this temporal, sinful world. As he healed the sick, set free the demon-possessed and forgave sins Eternity Himself demonstrated that His world is more powerful and real than the one we experience in our bodies. Ultimately He yielded to all that drags us down by dying on our behalf. He took the sting of death and rose triumphantly to open up the other world to all who would place their trust in Him. When you connect with Christ you plug in to another world--eternity and it changes you forever.
