The Lord Jesus Christ said in John 10: 10 that He came to give us life and that in abundance. This not only implies unending life in His salvation, but fullness of life even in a fallen world. Sadly many professing Christians do not seem to have the latter because they still have regrets, unforgiveness bitterness and all kinds of seeds that the devil sows in them to keep them from living fully for God and enjoying Him as they should. This of course is just another one of the enemy's tactics for discouraging believers when he can.
There is only ONE way to be a Christian!
