In Christianity, for a person to grow in godliness, he doesn’t need an instruction manual. What He needs to do is to behold and embrace Christ’s love for himself daily, and that inevitably starts maturing him. It is to grow in his understanding of God’s love for himself that begins to change the heart and causes him to have basic Christian virtues.
God promised Abraham of the inheritance he is going to receive. God promised Israel of the inheritance of the promised land that they are going to receive. God has always promised an inheritance to His people in the Bible, as a way of His loving assurance. All of His promises of inheritance are realized in Jesus Christ, and this itself is worth pondering over, for our entire life.
