John 10:10 The thief comes only in order to steal and kill and destroy. I came that they may have and enjoy life, and have it in abundance (to the full, till it overflows). AMPC
Jesus in this verse is clearly clarifying that He is the One who cares for us, He came to show us the good, abundant life we can life when we follow Him.
On the other hand if we follow the enemy we will allow him to kill, steal and destroy in our lives.
Our part then is to follow Jesus and there we will find rest. In rest we find peace not confusion, faith not fear, relation not worry, because we are following Him and we hear His voice and He in speaking His truth to us, will cause our hearts not to be troubled.
John 10:9 I am the Door; anyone who enters in through Me will be saved (will live). He will come in and he and he will go out [freely], and will find pasture. AMPC
