There are two parts to abundant life as spoken of in the Bible.
The first part takes place on this side of Heaven. The second part takes place in Heaven. Abundant life on this side of Heaven is a clean heart and holy life in the eyes of God. Abundant life in Heaven is an Eternal life with God everlasting.
In order to receive abundant life in Heaven one must first have and live with abundant life in Christ until death comes to the physical body; or the Church is Raptured to meet with Christ in the air.
