This is a hard truth but it remains the truth. There are times that God closes the Heaven as a means of disciplinary measures. Experiencing a closed Heaven could be in form of God keeping silence, closing Heaven against your prayers, living away from the dew of Heaven, etc. If you are experiencing a closed Heaven diagnose the cause and settle it with God.
God’s Grace is the good will, loving-kindness, favour, merciful kindness by which God, exerting his holy influence upon souls, turns them to Christ, keeps, strengthens, increases them in Christian faith, knowledge, affection, and kindles them to the exercise of the Christian virtues.
Some people are tempted to ask if God really exist because of what’s happening in our world today. Some have concluded that God does not care about the affairs of this world anymore. This is not true. God is supreme and His will is superior to all the wicked devices of the devil and his cohorts. Please listen to this message and you will understand that God is very much in charge of this world.
The love of Jesus Christ for the Church makes Him to correct believers whenever they are going astray. Those He loves He rebukes and chastens (Revelation 3:19). We are not to get discouraged when the Lord rebukes us, rather we should take it seriously and be happy because a child that is never disciplined is not a legitimate child.
