The picture of two trees represents the period of CREATION. God commands Adam not to eat from one of the trees, but Adam disobeys God, resulting in banishment from God's presence and death (Gen. 2-3). Since these two trees are at the very center of life in the garden, and since eating from one of them marks the entrance of sin into the world (Rom. 5), this picture is a reminder of these important events that take place in the period of CREATION.
The picture of a gift represents the period of ABRAHAM. In spite of Abraham's old age and Sarah's barrenness, Abraham believes that God is able to give him a son, as he has promised. God justifies Abraham, an ungodly person, on account of his faith (Gen. 15:6; Rom. 4). The picture of a gift underscores that justification is a gift of God by his grace.
The picture of the two stone tablets represents the period of SINAI. The Ten Commandments are the "stipulations" of the Mosaic covenant (Exod. 20; Deut. 5â6). God's people were required to keep these commandments; failure to keep them constituted "breaking" the covenant. The Ten Commandments serve as a reminder that the Law is given in this period and that it is central to God's covenant with Israel.
The picture of a blue crown represents the period of KINGS. Human beings are created in God's image to be his royal representatives (Gen. 1:26-28; Ps. 8). God's promise of kings to Abraham through Judah represents the continuation of the royal line, which will be realized through David's son whom God will raise up (Gen. 49:10; 1 Sam. 16; 2 Sam. 7).
The picture of a bird of prey represents the curses of the Mosaic covenant and the period of EXILE. God makes a covenant with Israel, promising to bless them if they obey his laws, but curse them if they disobey them (Lev. 26; Deut. 27â28). In 586 BC God's curses are poured out on Judah because they have disobeyed his laws (Jer. 7â11).
The picture of a temple represents the last period of the Old Testament known as TEMPLE. The picture recalls both the tabernacle (Exod. 25â40) and the temple built by Solomon in Jerusalem (1 Kgs. 6â8). The temple is destroyed in 586 BC by the Babylonians, but rebuilt after the exile in this final period, being completed in 516 BC (Ezra 6).
The picture of a blue crown inside a visionary cloud represents the period of EXPECTATIONS. God does not abandon His saving purposes, but builds expectations for a coming King in fulfillment of His promises to David (2 Sam. 7:12-17; Jer. 23:5-6). Israel eagerly awaits God's coming kingdom and the promised Messiah, who will bring forgiveness, restoration, and blessing to the nations (Dan. 7:13-14; Zech. 9:9; 14:9).
The picture of a blue crown represents the period of MESSIAH. God sends His beloved Son, Jesus, into the world. He is Israel's Messiah who had been promised many years earlier. Jesus proclaims the good news that God's kingdom has arrived (Dan. 2:44; Mark 1:14-15) and demonstrates the reality of the kingdom with signs, healings, and casting out demons (Isa. 35; Matt. 11; 12:28). Jesus calls people to repent, and believe in the gospel.
The picture of a fiery cloud represents the period of PENTECOST. After the death, resurrection and exaltation of the Messiah, God pours out His Spirit upon the church at Pentecost in fulfillment of His promises of old (Joel 2:28-29; Acts 2). Believers from all nations are filled with the Holy Spirit and are sanctified to walk in holiness and righteousness. Jesus extends His kingdom through the suffering and witness of the early church to Jerusalem, Judea and Samaria, and even to the ends of the earth (Ps. 2:6-8; Acts 1:8).
The picture of a scroll represents the period of TEACHING. The teaching ministry of the church continues as letters are sent to early Christian communities in an ever-expanding sphere of witness to the truth which is in Jesus (Eph. 4:21; John 14:6). Central teachings of New Testament include: Jesus is the Messiah; justification is by faith; the Holy Spirit indwells believers; Jew and Gentile are one in Christ; obedience comes through faith; believers are living sacrifices holy to the LORD; and Christ will return as Judge of the whole earth.
The picture of an open gate to the New Jerusalem represents the period of YET-TO-COME. The redemptive story that God began in the Garden of Eden ends with a city, which is inhabited by an innumerable multitude of people from every nation (Rev. 7). The glorious New Jerusalem comes down like a bride adorned for her husband (Rev. 21). Inside the gate, the water of life flows from God's throne and the tree of life is now accessible (Ezek. 47; Rev. 22). Evil is rightly condemned and the blessing of God's presence that had been lost in Eden is fully restored for all eternity (Gen. 2-3; Rev. 22).
