Pride is the great divider between the Creator and the creation. Pride says "I know better than You," "You can't make me," "I'll take it from here, God," "Thanks, but no thanks."
Insecurity says "Why did You make me this way?" "I am too unworthy for Your love," "I cannot ask You for help," "You cannot use me."
Those two may seem like whole different ball games but they both have the same underlying tone to them: "I don't need You" or "I'm better off without You." In essence: leave me alone.
Pride and insecurity tell God what He can and cannot do. It sounds so ludicrous when spelled out this way because it is! We, the created, have the audacity to tell our Creator a thing or two. It breaks the heart of God that we can be so wrong about our great need for Him because we are literally nothing without Him!
And here's the bottom line: He still loves us! Even after we've tried to live without Him for whatever reason. He is always waiting for us to recognize we have and are nothing without Him. God created us for Himself and He hates anything that comes between Him and the ones He loves. He is a jealous God. God wants us to turn and love Him because He has loved us (1 John 4:19). Everything He does is based on love--because God is love (1 John 4:16) and He knows no other way.
Pride and insecurity put space between a people and their God that was never meant to exist. God never wished for us to be seperate from Him so Jesus came to make things right again; so we could have a relationship restored unto Him. Pride would say "I'm above all that." Insecurity would say "I'm beneath all that." Truth would tell us we need Jesus. And He chases us to tell us so.
