This question is on the minds of many people.
Let’s start with your second question and the big picture. In Exodus 19:5, God tells the nation of Israel that "all the earth is mine." Let's think about that…God owns the earth. God has a purpose for this earth. Isaiah 45:18 (Amplified), “For thus says the Lord Who created the heavens, God Himself Who formed the earth and made it, Who established it and created it not a worthless waste; He formed it to be inhabited…”
So, what will God do with this earth? Isaiah 35 says He will make the earth fruitful and beautiful; He will take away all mankind’s illnesses, blindness, deafness, etc. He will establish peace, justice and righteousness.(Isaiah 26:9) God loves all the people of the world, and plans to bless them. This is the Gospel the Apostle Paul writes about in Galatians 3:8, ”The Scripture, foreseeing that God would justify the Gentiles by faith, preached the gospel beforehand to Abraham, saying ‘All the nations will be blessed in you.’"
Why is the number of Moslems growing? Will it come to the point where Moslems will take over the world? No. Just before the blessing of all mankind comes Armageddon (the final climatic battle of all nations), but then Christ’s kingdom of peace will be established. Presently, these severe troubles are multiplying in every aspect of life: governments, environment, finances, food shortages, diseases, mental health, etc. The increase in wars may be one of the methods the Lord permits to ignite Armageddon. However, you do not need to be afraid, because Matthew 24:22 tells us that "unless those days had been cut short, no life would have been saved but for the sake of the elect those days WILL be cut short."
So we do not need to be afraid of what we see. Zephaniah 2:3 reads, ”Seek the Lord, all you humble of the earth who have carried out His ordinances; Seek righteousness, seek humility. Perhaps you will be hidden in the day of the Lord's anger." It is always wise to humbly ask God to guide and protect you.
Then the blessings mentioned above WILL happen. The time will come spoken of in the Lord’s prayer, “Your (God’s) kingdom come. Your will be done, On earth as it is in heaven.” Matthew 6:10
