Summary: There is a fundamental difference of me looking directly into my sons eyes and saying, "You are my beloved son," and if I were to put my arm around him and say to you, "this is my beloved son." One is a private declaration, one is a public demonstration.
This is Thou Art
Luke 3:21-22 (quickview)  Now when all the people were baptized, it came to pass, that Jesus also being baptized, and praying, the heaven was opened, And the Holy Ghost descended in a bodily shape like a dove upon him, and a voice came from heaven, which said, Thou art my beloved Son; in thee I am well pleased.
Matthew 17:5 (quickview)  While he yet spake, behold, a bright cloud overshadowed them: and behold a voice out of the cloud, which said, This is my beloved Son, in whom I am well pleased; hear ye him.
In our texts today I want you to notice a subtle but important difference between them. In Luke the bible records God the Father as speaking to Jesus, and in Matthew the bible records God speaking about Jesus.
Hence the title of this message: "This is; Thou Art."
We have a fundamental need to have both of these statements said to and about us.
Illus: (Have one of my sons stand with me.) There is a fundamental difference of me looking directly into my sons eyes and saying, "You are my beloved son," and if I were to put my arm around him and say to you, "this is my beloved son."
One is a private declaration, one is a public demonstration. You need, and God wants to give us both private assurance of, and a public demonstration of His love for us.
1. Thou art My beloved son.
Thou art My beloved son is a private declaration of God’s love for you.
Everyone has a fundamental need to know that God loves them, and that if they die they will go to heaven. It will add faith to your prayers, hope to your darkest hour, and the love we all so desperately need to have a fulfilling life.
The bible tell us to be ready for in an hour we think not our Lord will come for us. It is not enough to think you are saved or to hope you are saved. We have a fundamental need to have heard God say, thou art my beloved son/daughter in whom I am well pleased.
2 People in contrast: Luke 12:19-20 (quickview) , Psalms 35:3 (quickview) . One spoke to himself the other prayed God would assure him. In Luke the rich man speaks to himself about building new barns and tells himself what a great job he has done in life.But God called him a fool and said that night his soul would be required of him.
By contrast in Psalms 35:3 (quickview)  David prays, "Say to my soul, ’I am thy salvation.’" Tis a wise thing in deed to be sure that you are sure. It is not enough to tell yourself you are saved and all is well. You need a personal communication from God that you are saved. The bible says that His Spirit bears witness with our spirit that we are the children of God. Don’t have an "I think I’m saved," but press in for an "I know I’m saved."
God personally spoke to and assured Abraham of his salvation: Genesis 15:1 (quickview)  After these things the word of the LORD came unto Abram in a vision, saying, Fear not, Abram: I [am] thy shield, [and] thy exceeding great reward. If you are saved God will assure you of it, if you are doubting don’t rest until you have assurance.
2. This is My beloved son.
This is My beloved son, is a public declaration of God’s love for you.
