Satan cannot create anything. God is our creator, and we are His created beings. For You (God) created my inmost being; You knit me together in my mother’s womb. I (David) praise You for I am fearfully (awesomely) and wonderfully made (Psalms 139:13-18). So God created man in His own image, in the image of God (in God’s likeness) He created him; male and female He created them. God blessed them and said, “Be fruitful (productive) and increase in number. (Genesis 1:27, 28a) Therefore, God, (God the Father, God the Son, God the Holy Spirit) is creative, fruitful and rules over all things as our creator God. In the beginning was the Word, and the Word was with God, and the Word was God. He (Yeshua Messiah) was with God (Father God and Holy Spirit of God) in the beginning. Through Him all things were made, without Him nothing was made that was made (1 John 1:1-3). The Word is God and also is the words that God speaks, by which He created the world and governs it.
God created you and me, and because we are created by Him, we are precious, of great worth. We are so precious to God that God sent Jesus Christ to suffer, die, and be raised from the dead to redeem us from Satan’s lies and deception. For everything God created is good and it is to be received with thanksgiving and not rejected (1 Timothy 4:4-5). That includes receiving and loving ourselves and, like David, praising God for making us awesome and wonderful.
Nothing can negatively change or diminish our value. Solomon wrote: “I know that everything God does will endure forever, nothing can be added to it and nothing taken from it. God does it so that men will revere Him (Ecclesiastes 3:14). Since God made us of great value and whatever God creates cannot be added to increase our value or taken from us to devalue us in any way. That means that when I sin, my value does not go down, and when I do good things, my value does not go up. It is fixed. It does not change.
All (God’s) words are true (Psalm 119:160). The Lord speaking to His disciples and to all believers says, “Sanctify, make them whole, that is holy, by the truth.”
