The Thief - Who comes to kill
John 10:10 "The thief does not come except to steal, and to kill, and to destroy. I have come that they may have life, and that they may have [it] more abundantly. (NKJV)
Jesus came to give us life. When you received Jesus you received the right to become the Child of God (John 1:12). Satan however wants to kill your relationship with God. He does not want you to remain in the Christian faith or spend an eternity with God.
The aim of every temptation, trial and sin satan brings your way is the same; to lure you away from Jesus.Satan knows that he cannot take you away from Jesus by force or against your own will (John 10:28-29).
Instead he concentrates his efforts in deceiving you into thinking that God is not faithful (or powerful enough) and therefore not worth serving. Once Satan can get you to "give up" in your efforts to serve God, he knows that he can then tempt you to depart from the faith.
Satan cannot take you away from God by force, but he will attempt to get you so offended with God, with the hope of getting you to depart from the love of Jesus of your own accord (1 Timothy 4:1).
The next time satan or any of his demons bring any of their dirty tricks along your way, like sowing doubt in your mind about the goodness of God or putting sickness or depression on you, don't just sit there wondering why God allowed it.
Stand up against satan (2 Corinthians 10:3-7), tell him you know what his aim is; to kill your relationship with God. Let him know that whatever he brings along your way, you will never depart from the faith, then use your God given authority to resist him (1 Peter 5:8-9)
Remember, satan's main objective is to get you to depart from the faith. This is what Jesus meant when he said
John 10:10 "The thief does not come except to steal, and to kill,....." (NKJV)
Satan steals by concealing from us the privileges we have in Jesus Christ. He kills by deceiving us into departing from God.
This is why it is so important that we do not play with sin. It's true that when we do sin God forgives us when we repent (1 John 2:1-2).
But the danger of continuously falling into sin is that we might decide to stay there. This could eventually lead to our departing from the faith (Hebrews 3:12-15).
