On the occasion that Christ appears God expects us to celebrate our life in Christ. A true Christian's heart draws to eternity. Our Lord is there, our home is there, our wealth is there. Since our hope is there, we will be there for ever. This is the point when the believer will receive ultimate sanctification.
Ultimate sanctification involves a new body and a soul separated from sin and the capacity to sin.
The best is yet ahead for the Christian. Meanwhile we should set our hearts on things above. We need to cultivate a taste for eternity and fellowship with God. We cultivate that taste by study of God's Word. Many have lost their appetite for the Word of God.
