Man, by nature, is afraid of God. When Adam first sinned, he should have gone immediately to God to beg for mercy and forgiveness. Instead he did just what millions are doing today: he ran and hid from God so that God had to come and look for Him, as it were, calling: "Adam... where art thou?" (Gen. 3:9).
Many people who consider themselves as good, morally, as those about them, or even better, nevertheless feel utterly ill-at-ease in a place of worship, where believers pray and praise God together. This is because in their heart of hearts they know that they have "sinned and come short of the glory of God" (Rom. 3:23).
Such, however, may come to know, love and enjoy God through faith in Christ. He was Himself God manifested in the flesh, come to earth in love to pay for our sins on Calvary's cross, so that we might have "redemption through His blood, the forgiveness of sins according to the riches of His grace" (Eph. 1:7).
Concerning those who respond in grateful faith and trust in the crucified, risen, glorified Lord for salvation, the Apostle Paul says:
"Therefore, being justified by faith, we have peace with God through our Lord Jesus Christ; by whom also we have access by faith into this grace wherein we stand, and rejoice in hope of the glory of God" (Rom. 5:2).
Peace with God, and the fellowship which naturally results from this is the most precious treasure the human heart can contain. Yet our fellowship with Him here on earth is but the beginning. Read carefully Ephesians 5:25-27 and see how He took upon Him human form, and died, that He might have us for Himself forever:
"...Christ... loved the Church, and gave Himself for it... that He might present it to Himself a glorious Church, not having spot, or wrinkle, or any such thing; but that it should be holy and without blemish."
