God remembers and He wants us to remember. The Lord remembered that He had made a promise to Adam. The rest of the Bible is the history of Him doing what He said He would do. He never forgot because God remembers His promises.
Genesis 3:15 And I will put enmity
Between you and the woman,
And between your seed and her seed;
He shall bruise you on the head,
And you shall bruise him on the heel.”
God remembered Noah.
Genesis 8:1 But God remembered Noah and all the beasts and all the cattle that were with him in the ark; and God caused a wind to pass over the earth, and the water subsided.
God remembered all flesh and made a promise not to flood the earth again. He gave us the rainbow as a testimony of His promise to every living creature of all flesh.
Genesis 9:16 When the bow is in the cloud, then I will look upon it, to remember the everlasting covenant between God and every living creature of all flesh that is on the earth.
God remembered His covenant that He had made with Abraham, Isaac and Jacob.
Exodus 6:5,6 Furthermore I have heard the groaning of the sons of Israel, because the Egyptians are holding them in bondage, and I have remembered My covenant. Say, therefore, to the sons of Israel, ‘I am the Lord, and I will bring you out from under the burdens of the Egyptians, and I will deliver you from their bondage. I will also redeem you with an outstretched arm and with great judgments.
The Lord remembered His promise to send a Savior, who would be born of a virgin and His name would be Immanuel, which means “God with us”.
Isaiah 7:14 Therefore the Lord Himself will give you a sign: Behold, a virgin will be with child and bear a son, and she will call His name Immanuel.
God remembered us. He sent His Beloved Son so that we might be saved. He did not send Jesus into the world to judge us but that we might be saved through Him.
John 3:16,17 For God so loved the world, that He gave His only begotten Son, that whoever believes in Him shall not perish, but have eternal life. For God did not send the Son into the world to judge the world, but that the world might be saved through Him.
Even though we are prone to forget the Lord wants us to remember. He wants us to remember the cross and the price that was paid for our salvation. He wants us to remember that He forgave us and freed us from slavery to sin. He wants us to remember the great things that He has done for us. He does not want us to forget. He wants us to pass on to the next generation what He has done. The purpose of the Lord’s supper is to remember the cross and His death.
I Corinthians 11:23-26 For I received from the Lord that which I also delivered to you, that the Lord Jesus in the night in which He was betrayed took bread;and when He had given thanks, He broke it and said, “This is My body, which is for you; do this in remembrance of Me.” In the same way He took the cup also after supper, saying, “This cup is the new covenant in My blood; do this, as often as you drink it, in remembrance of Me.” For as often as you eat this bread and drink the cup, you proclaim the Lord’s death until He comes.
Every time we thank Him in prayer we are remembering His great goodness to us. Every time we take the Lord’s supper we are remembering what He did for us. Every time we share the Gospel we are remembering His love for us and not only us but His love for the world.
I Corinthians 15:1-4 Now I make known to you, brethren, the gospel which I preached to you, which also you received, in which also you stand, by which also you are saved, if you hold fast the word which I preached to you, unless you believed in vain. For I delivered to you as of first importance what I also received, that Christ died for our sins according to the Scriptures, and that He was buried, and that He was raised on the third day according to the Scriptures,
He says that if we are not ashamed of Him and His Word then He will not be ashamed and remember us when He comes again. Are you remembering Him by proclaiming Him?
Mark 8:38 For whoever is ashamed of Me and My words in this adulterous and sinful generation, the Son of Man will also be ashamed of him when He comes in the glory of His Father with the holy angels.
