What is the kingdom of God? The word “kingdom” means something more than a territory or an area of land. It literally means “sovereignty” or “reign” and the power to “rule” and exercise authority. The prophets announced that God would establish a kingdom not just for one nation or people but for the whole world. The Scriptures tell us that God’s throne is in heaven and his rule is over all (Psalm 103:19). His kingdom is bigger and more powerful than anything we can imagine because it is universal and everlasting (Daniel 4:3). His kingdom is full of glory, power, and splendor (Psalm 145:11-13).
How do we enter the kingdom of God? In announcing the good news, Jesus gave two explicit things each of us must do to in order to receive the kingdom of God: repent and believe. When we submit to Christ’s rule in our lives and believe the gospel message the Lord Jesus gives us the grace and power to live a new way of life as citizens of his kingdom. He gives us grace to renounce the kingdom of darkness ruled by sin and Satan, the father of lies (John 8:44) and the ruler of this present world (John 12:31). That is why repentance is the first step.
Repentance means to change – to change my way of thinking, my attitude, disposition, and life choices so that Christ can be the Lord and Master of my heart rather than sin, selfishness, and greed. If we are only sorry for the consequences of our sins, we will very likely keep repeating the sin that is mastering us. True repentance requires a contrite heart (Psalm 51:17) and sorrow for sin and a firm resolution to avoid it in the future. The Lord Jesus gives us grace to see sin for what it really is – a rejection of his love and wisdom for our lives and a refusal to do what is good and in accord with his will. His grace brings pardon and help for turning away from everything that would keep us from his love and truth.
