The heavens declare the glory of GOD; and the firmament sheweth His handywork. Day unto day uttereth speech, and night unto night sheweth knowledge. There is no speech nor language, where their voice is not heard. Their line is gone out through all the earth, and their words to the end of the world. In them hath He set a tabernacle for the sun, Which is as a bridegroom coming out of his chamber, and rejoiceth as a strong man to run a race. His going forth is from the end of the heaven, and his circuit unto the ends of it: and there is nothing hid from the heat thereof. (Psalms 19:1-6)
GOD does not hide Himself, or His work, and only the foolish reject Him and His revelation of Himself through nature. But nature, being cursed by our sIn, is only the general revelation of GOD as Creator and Provider. GOD further reveals Himself through His Word that is more sure than even the sun coming up each day. One day there will be no more sun, but GOD's Word will remain.
As long lasting as this world seems to be, it will have an end, just as it had a beginning. But GOD, who is eternal and outside His creation, will never end, and we who are alive in Christ, will live forever with Him. We are promised this because of His love, and our faith in His finished work on the Cross of Calvary.
Those that don't know Jesus Christ are promised a different eternity, because they have not yet been born again. Jesus loves you and wants to establish a covenant relationship with you that is real and personal. He is not willing that you should perish, but wants you to repent of your sIn. Surrender to Him on His terms and be born again. Believe in Him and receive by faith a brand new life of discipleship and fellowship that is abundant and everlasting.
Trust His Word and His revelation of Himself, and His Salvation that is provided and freely offered to you.
