There is not one verse in the Bible that encourages you to ask, "Why?".
You were designed to walk by faith. Faith does not need all the explanations, nor does faith decide if God's reason is acceptable. To question God is to assume that your reasoning and insight is equal to His.
Soldier, a living sacrifice does not lay on the alter, holding up a list of objections or demands. It is one thing to pray through the Work of the Lord. It is another thing to question the Sovereignty of God. He is not insecure and does not suffer from the lack of faith. It Is you who will suffer.
We have the Word of God. We have the Body of Christ. We have the assurance of Salvation. We also have Power because the Indwelling Holy Spirit lives within us and empowers us to obey.
What is your priority? Is it faith? After all, there is no other way to know God. Is there anything else that is a close second? Of course not. The issues of this life must match the issues of eternity.
You must tell Him aloud. He will assure you by the very words that the Holy Spirit will give you in prayer.
