Life in Heaven is the supreme goal of our life on earth.   Desiring Heaven is brought about by the theological virtue of hope.  Our longing for Heaven, and our capacity to reach it, is tied to our love of God in this life.  We must learn to love God as our happiness in this life if we wish to enter eternal life confidently.  Hope helps us avoid despair on the one hand, whenever we see the depth of our sinfulness, and keeps presumption at bay on the other hand, whenever we are tempted to falsely "exaggerate" God's mercy.  https://comeawaybyyourselves.com
