Does Almighty God see the future? why do we have to pass through temptations when Almighty God knows the final, I mean, He knows if we will pass or fail.
You are tip toeing through a mine field with your questions.
You are assuming that temptation comes from God. It does not.
You are assuming that temptation will defeat the devoted Christian. It will not.
God knows we shall overcome the temptations of the flesh.
First, let's get a few things established. Then we'll address your question in depth.
God does not SEE the future, He MAKES it.
I am the Alpha and the Omega, saith the Lord God, which is and which was and which is to come, the Almighty. Rev 1:8
When people build their own philosophy or theology, they rarely consider God as part of it.
Usually He is off to one side as a sort of figure or affectation or scape goat.
This is quite wrong because God is intimately involved in His creation. He is not off to one side as an observer. He is not resting.
God creates the future and includes or excludes people in it according to certain criteria.
One of those criteria is the human response to Him.
The inclusion is also called life and the exclusion is called death.
Many men have shortened their lives because they rebelled against God.
Many have preserved and lengthened their lives because they surrendered to God's good will.
Rebellion against the will of God takes two forms; failure to Love Him most of all and failure to love our neighbor.
The rebellion begins in self-will and is exacerbated by an external force. It ends in sin.
The mechanism takes the form of a
contest of the will. This contest of the human will is also called temptation.
To answer your question,
we do not HAVE TO pass through temptation, we CAUSE ourselves to do so.
Let no man say when he is tempted, I am tempted of God: for God cannot be tempted with evil, and he himself tempteth no man:
but each man is tempted, when he is drawn away by his own lust, and enticed. - James 1:13-14
Note here that it says men are tempted by their own lusts.
If a man abandons his lusts then all things change for him. Its as simple as that.
Does God plot ahead of time that we will fail or lay traps for us? No.
The scripture above tells us the truth that God does not plot ahead of time for our failure.
I have lived many years with the Lord and can testify along with millions of Christians that God has NEVER tempted me.
But there are spiritual forces that do indeed tempt men for the purpose of luring them to their destruction.
Will we fail in Christ?
NEVER.
Anyone who says that yielding to temptation is inevitable is in deep rebellion against God.
But Jesus said unto him, No man, having put his hand to the plow, and looking back, is fit for the kingdom of God. Luke 9:62
Temptation is NOT from God. Failure from temptation is NOT inevitable and no Christian will bear temptation alone.
There hath no temptation taken you but such as man can bear: but God is faithful, who will not suffer you to be tempted above that ye are able; but will with the temptation make also the way of escape, that ye may be able to endure it. 1Co 10:13
This 'temptation' or contest of the will, cannot and will not be lost, nor will it yield if it is devoted to Christ.
