When we come to grips that God so Loved us, that He gave His only begotten Son to die for our sins and then guarantees us by His resurrection, that if we accept Jesus Christ we have Everlasting Life (St. John 3: 16, 36). Finally, knowing that in our life we will get out of fellowship with God because of sin. Thanks be to God that He has given us instructions on how to be restored into His Fellowship and in good standings with Him (1 John 1: 9).
St. John 3:16
16For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life.
