There are things that we can lay hold of this side of glory. The best is yet to come! Since we have the Holy Spirit inside of us, there is NO reason why a Christian should have a defeated life. The Holy Spirit enables us to press on.
If we want to experience the fullness that the Lord has for us, the only way is to PRESS ON AND DEVELOP A PRESSING SPIRIT. You have to have a desire/flame/hunger for the Lord.
