2 chronical 1:3-6
“3 and Solomon and the whole assembly went to the high place at Gibeon, for God’s tent of meeting was there, which Moses the Lord’s servant had made in the wilderness. 4 Now David had brought up the ark of God from Kiriath Jearim to the place he had prepared for it, because he had pitched a tent for it in Jerusalem. 5 But the bronze altar that Bezalel son of Uri, the son of Hur, had made was in Gibeon in front of the tabernacle of the Lord; so Solomon and the assembly inquired of him there. 6 Solomon went up to the bronze altar before the Lord in the tent of meeting and offered a thousand burnt offerings on it.”
John 15:1-17
“I am the true vine, and my Father is the gardener. 2 He cuts off every branch in me that bears no fruit, while every branch that does bear fruit he prunes[a] so that it will be even more fruitful. 3 You are already clean because of the word I have spoken to you. 4 Remain in me, as I also remain in you. No branch can bear fruit by itself; it must remain in the vine. Neither can you bear fruit unless you remain in me. 5 “I am the vine; you are the branches. If you remain in me and I in you, you will bear much fruit; apart from me you can do nothing. 6 If you do not remain in me, you are like a branch that is thrown away and withers; such branches are picked up, thrown into the fire and burned. 7 If you remain in me and my words remain in you, ask whatever you wish, and it will be done for you. 8 This is to my Father’s glory, that you bear much fruit, showing yourselves to be my disciples. 9 “As the Father has loved me, so have I loved you. Now remain in my love. 10 If you keep my commands, you will remain in my love, just as I have kept my Father’s commands and remain in his love. 11 I have told you this so that my joy may be in you and that your joy may be complete. 12 My command is this: Love each other as I have loved you. 13 Greater love has no one than this: to lay down one’s life for one’s friends. 14 You are my friends if you do what I command. 15 I no longer call you servants, because a servant does not know his master’s business. Instead, I have called you friends, for everything that I learned from my Father I have made known to you. 16 You did not choose me, but I chose you and appointed you so that you might go and bear fruit—fruit that will last—and so that whatever you ask in my name the Father will give you. 17 This is my command: Love each other."
The Answer
is John 15 Because Jesus is greater than Moses and Solomon. All believers are like branches from a tree perfectly connected to Jesus as the root. Jesus is greater than the temple in his day, greater than all the Old Testament prophets. However, Jesus said “Do not think that I have come to abolish the Law or the Prophets; I have not come to abolish them but to fulfill them. 18 For truly I tell you, until heaven and earth disappear, not the smallest letter, not the least stroke of a pen, will by any means disappear from the Law until everything is accomplished." So, Jesus is greater than anyone in the Old Testament. The Old Testament is still important for people to study because Jesus fulfilled the Old Testament prophecies.
