John 15:7 KJV
If ye abide in me, and my words abide in you, ye shall ask what ye will, and it shall be done unto you.
I liked what Scofield's Notes has to say about abiding;
"To abide in Christ is, on the one hand, to have no known sin unjudged and unconfessed, no interest into which He is not brought, no life which He cannot share. On the other hand, the abiding one takes all burdens to Him, and draws all wisdom, life and strength from Him. It is not unceasing consciousness of these things, and of Him, but that nothing is allowed in the life which separates from Him. "
It must be the desire of every believer that we abide in Christ and that His words abide in us. In the world in which we find ourselves we must allow our minds to occupied with thoughts other than of Christ and the Word of God.
We must concentrate on our families and give them time and attention
We must reach out to others and give them care and concern
We must be honest with our employer and give them due diligence on the job
But even thought there are times when our mind may not be able to be fully devoted to thoughts of Christ and meditations of Scripture there is no moment in the life of the believer when we need to be separated from Christ and His Word through unconfessed sin or other things that cause a separation from the Lord.
