The method God has chosen for believers to help each other grow into maturity is discipleship. To grow as a disciple involves more than developing certain disciplines and acquiring essential knowledge. It includes working through life with all of its difficulties and pleasures. This progressive sanctification is done in community with other believers as we share the comfort they receive from the Lord himself.
Grace and peace to you from God our Father and the Lord Jesus Christ. Praise be to the God and Father of our Lord Jesus Christ, the Father of compassion and the God of all comfort, who comforts us in all our troubles, so that we can comfort those in any trouble with the comfort we ourselves receive from God. (2 Corinthians 1:2-4 NIV)
Jesus never promised an easy life. Instead, he equips us for life as it really is. He does so by giving us himself personally.
