Salvation is HARD WORK

Salvation will take extremely hard work on your and my part IF we make it through the narrow door into the kingdom of Heaven. Jesus said:”Strive hard, for many I tell you will try and not be able.” You will have to try your utmost and then you still might not be able to find the narrow door. 
Without Jesus, you won't make it. If you do not deny yourself EVERY DAY, pick up your cross and follow Jesus you won't make it. Jesus has no part-time followers. You have to follow Him every day. You have to work on your relationship with Him ALL THE TIME, every moment. You must be focused on Him and on doing His will all the time. If you are not working and striving for the kingdom of God then you are breaking it down. If you are not gathering, you are scattering. If your focus is not on Jesus and if you are not led by the Holy Spirit then you are led by your own flesh and by the devil. That which is of the flesh is flesh and that which is of the Spirit of God  is Spirit. You must be led by the Spirit of God.
You cannot go sit in a corner, read your Bible and be holy. You have to GET UP and FOLLOW Jesus AFTER YOU HAVE PRAYED and sought Him in prayer. You have to seek Him always, day and night. You must seek Him in prayer, you must HEAR from Him. If you are not led by the Spirit of God you are not a child of God. If you do not have the Spirit of Christ in you, BURNING LIKE A FIRE, you are dead. 
It is not easy to enter the kingdom of Heaven. Very few will make it. Strive hard, get your focus on Jesus and follow Him every moment. Cry out to Him, seek Him and DO what He tells you to do, every day, or else you will not find that narrow door. It is HARD WORK to enter the kingdom of Heaven and very few will make it. 
May Jesus bless you.
