The WCF says very clearly the following...
CHAP. III. - Of God's Eternal Decree.
1. God from all eternity, did, by the most wise and holy counsel of His own will, freely, and unchangeably ordain whatsoever comes to pass: yet so, as thereby neither is God the author of sin, nor is violence offered to the will of the creatures; nor is the liberty or contingency of second causes taken away, but rather established.
and this...
CHAP V. - Of Providence.
1. God the great Creator of all things doth uphold, direct, dispose, and govern all creatures, actions, and things, from the greatest even to the least, by His most wise and holy providence, according to His infallible foreknowledge, and the free and immutable counsel of His own will, to the praise of the glory of His wisdom, power, justice, goodness, and mercy.
Explain the contradiction AMR.
I will explain the two sections since you apparently don't understand them.
There is no contradiction to explain, however.
III.1
This section and article is best understood when persons have a proper understanding of some key terms.
Foreknowledge means that God knows always and at all times everything which is to come to pass.
Foreordination means that the divine ordination is related in some way or other to all that happens. Foreordination implies to arrange beforehand, to predispose all events and their conditions in such a manner that all shall come to pass according to God's eternal plan. Foreknowledge and foreordination are related: God foreknows events because God has prearranged the happening of these events. To admit foreknowledge carries foreordination with it.
Predestination means to bound or limit, and thus to fix definitely the occurrence of any event. For Calvinists, predestination is used to express the plan of God as it relates to the acts and destiny of moral agents. Importantly, the term is always applies to the elect, and
never to the non-elect. Ordination is the term used for the non-elect. In other words,
the elect are predestinated to life and the non-elect are ordained to death.
Election is a term applied to the heirs of salvation, meaning selected, designated, or chosen out. Election relates to God’s gracious plan or purpose to save certain persons through Christ, and by the appointed means.
Reprobation does not appear in the confessional standards, but it has been a common term used in much theological discussions. As noted below, the confessional standards speak of the non-elect being
passed by and left in their sin. The often used and best word to express this fact is the word
preterition, or passing-by. The non-elect are passed by and left in condemnation because of their sins.
From your underlined emphasis above, the key summary is that
God has ordained, that is, arranged beforehand, to predispose all events and their conditions in such a manner that all shall come to pass according to God's eternal plan.
Before moving to the second section and article you have quoted, to answer your earlier question about foreknowledge and the decrees, please review the second article in this section, which reads:
"2. Although God knows whatsoever may or can come to pass upon all supposed conditions, yet
hath He not decreed any thing because He foresaw it as future, or as that which would come to pass upon such conditions."
God's foreknowledge does not enter into consideration for His decrees. God foreknows what should be because He decrees that they should be. God did not decree anything because He foresaw it as future. Moreover, the execution of God's decrees is not conditional. This is the explicit doctrine which distinguishes Calvinists from Arminians, who hold that God's decrees are not absolute but conditional.
V.1
To better understand this section, another term must be defined:
Providence is God’s most holy, wise, and powerful
preserving and
governing all his creatures and all their actions to His own glory.
In this section and article we find the discussion moving forward from God's decrees to their execution, from God's eternal purpose to the realization of this purpose in time, from God's comprehensive plan to its actual coming to pass. In summary, God executes His decrees, realizes His purpose, or carries out His plan in the works of creation and providence. This is all done according to God’s exhaustive foreknowledge, and the free and immutable counsel of God's own will.
God's providence is about God, the creator all things, preserving His works.
One section of the WCF describes God's ordaining whatever comes to pass, the other describes God's providence sustaining and preserving God's works.
