The Kingdom of Heaven is not merely about going to Heaven when we die, but also about living under God's rule now. There are three stages of salvation: justification (becoming a Christian), sanctification (growing in holiness), and glorification (being perfected in Heaven). Many believers focus solely on justification but neglect sanctification. This neglect can lead to unpreparedness for Christ's return or our own death. We must actively pursue spiritual growth, eagerly awaiting His return. The delay in Christ's coming is a grace period for us to deepen our relationship with Him. Our goal should be to know more intimately, not just to secure a place in Heaven.
