Galatians 4:1-7 (New International Version)

Galatians 4:1

What I am saying is that as long as the heir is a child, he is no different from a slave, although he owns the whole estate. 2He is subject to guardians and trustees until the time set by his father. 3So also, when we were children, we were in slavery under the basic principles of the world. 4But when the time had fully come, God sent his Son, born of a woman, born under law, 5to redeem those under law, that we might receive the full rights of sons. 6Because you are sons, God sent the Spirit of his Son into our hearts, the Spirit who calls out, "Abba,[a] Father." 7So you are no longer a slave, but a son; and since you are a son, God has made you also an heir.

AS long as one is a child one cannot receive or make claim of his inheritance from his father .As Christians sometimes we don't understand why we fall victims to some circumstances or find ourselves in some situation. We read daily of promises and blessings made available to us from the Bible but cant experience it in our lives some of us go to extent of blaming God instead of analyzing our lives to check our level of maturity as a Christian. From the above verse Paul makes us understand that as a child you do not differ from a slave boy. Yes you can be a heir to the possessions of your father but until the appointed time when you become matured or old enough you cannot take charge of things.
