"But sanctify the Lord God in your hearts: and be ready always to give an answer to every man that asketh you a reason of the hope that is in you with meekness and fear"
(I Peter 3:15).

The writer of the book of Ecclesiastes reminds us that all things must change.  "To every thing there is a season, and a time to every purpose under the heaven" (Ecclesiastes 3:1).

Throughout the Old Testament, God often reminded His children to remember His mighty acts on their behalf. Sometimes visible memorials were set up to facilitate their recall, such as the pile of stones taken from the middle of the Jordan River when God held back the waters to allow them to enter the Promised Land (Joshua 4:6).

"Hear, O my people, and I will testify unto thee: O Israel, if thou wilt hearken unto me. . . . open thy mouth wide, and I will fill it" (Psalm 81:8,10).

"If we confess our sins, He is faithful and just to forgive us our sins, and to cleanse us from all unrighteousness" (I John 1:9).
