Infants and mentally disabled. Salvation issue

I always believed that Infants, dying in infancy, including those who are mentally disabled are regenerated, and saved by Christ, through the Spirit, (Luke 18:15-17) who works when, and where, and how He pleases: so also are all others who are incapable of being outwardly called by the ministry of the Word. I have to remember that God is in control and He KNOWS every heart and knows all of us before we were born. Sovereign God is the absolute, infinite, unqualified ruler in all realms in heaven, earth and sea. God is to be Lord over all the creation, He is omnipotent, He is omniscient, He is omnipresent. He knows every little details and He has already planned out our tomorrows and He is holding the world in the palm of His hand. Sovereignty and omnipotence are together that one cannot exist without the other. Luke 18:15-17 People were also bringing babies to Jesus to have him touch them. When the disciples saw this, they rebuked them. But Jesus called the children to him and said, "Let the little children come to me, and do not hinder them, for the kingdom of God belongs to such as these. I tell you the truth, anyone who will not receive the kingdom of God like a little child will never enter it." Romans 8:28-29"And we know that God causes everything to work together for the good of those who love God and are called according to his purpose for them. For God knew his people in advance, and he chose them to become like his Son, so that his Son would be the firstborn, with many brothers and sisters. The Apostle Paul wrote, “Oh, the depths of the riches of the wisdom and knowledge of God! How unsearchable His judgments, and His paths beyond tracing out!” (Rom 11:33) “God knows instantly and effortlessly all matters, all mind and every mind, all spirits, all being and every being, all creaturehood and all creatures, every plurality and all pluralities, all law and every law, all relations, all causes, all thoughts, all mysteries, all enigmas, all feeling, all desires, every uttered secret, all thrones and dominions, all personalities, all things visible and invisible in heaven and in earth, motion, space, time, life, death, good, evil, heaven, and hell…” A. W. Tozer The Bible clearly teaches that God knows beforehand what everyone will need and He will provide beforehand according to His will. Wisdom sees everything in focus and be able to trust God no matter what happens. All God's acts are done in perfect wisdom for His own glory.
