Psalm 63:8 "My soul followeth hard after thee: thy right hand upholdeth me."
Someone made the statement..."The main thing is to keep the main thing the main thing." It isn't an easy thing. We are constantly being pulled in many directions.
The main thing is to maintain a right relationship with God. A person could pray everyday...read his/her Bible...attend church...and be separated from the world...yet his/her heart not be right with God. A good example of this was the Pharisees. They prayed (Matthew 23:14 "Woe unto you, scribes and Pharisees, hypocrites! for ye devour widows' houses, and for a pretence make long prayer:") ....read the scriptures...engaged in winning others (Matthew 23:15 "Woe unto you, scribes and Pharisees, hypocrites! for ye compass sea and land to make one proselyte, and when he is made, ye make him twofold more the child of hell than yourselves.") ...tithed (Luke 18:12 "I fast twice in the week, I give tithes of all that I possess.") ...and they were separated from the world (Luke 18:11 "The Pharisee stood and prayed thus with himself, God, I thank thee, that I am not as other men are, extortioners, unjust, adulterers, or even as this publican.") . They were right externally...but their heart was not right. Jesus said of the Pharisees in Matthew 23:28 "Even so ye also outwardly appear righteous unto men, but within ye are full of hypocrisy and iniquity."
When the heart is right with God...the external things will follow suit. It begins with salvation...until you are saved you have no relationship with God. It breaks with sin. Just as one small "glitch" in a computer program will cause it to crash...so will sin cause your fellowship with God to be broken. It is blessed with surrender. God only blesses what is given to Him. Anything we withhold from Him...can't receive His blessing.
Like any other relationship in life...your relationship with God must be maintained. You must invest some time into it. How's your relationship with God?
