Human memory is really amazing. Studies said that there are two levels of memory, one is short-term memory, which is a way to store information temporarily. It lasts about 15 to 30 seconds. The other is long-term memory, which can store information for longer periods. It can last days, months, years, or a lifetime. The brain also forgets information that it no longer needs. Here is something amazing, God said He will not remember our sins when we come to Him for forgiveness. Isn´t that wonderful?
