Romans 1:11 For I long to see you, that I may impart to you some spiritual gift, so that you may be established— 12 that is, that I may be encouraged together with you by the mutual faith both of you and me.
Colossians 2:4 Now this I say lest anyone should deceive you with persuasive words. 5 For though I am absent in the flesh, yet I am with you in spirit, rejoicing to see your good order and the steadfastness of your faith in Christ. 6 As you therefore have received Christ Jesus the Lord, so walk in Him, 7 rooted and built up in Him and established in the faith, as you have been taught, abounding in it with thanksgiving. 8 Beware lest anyone cheat you through philosophy and empty deceit, according to the tradition of men, according to the basic principles of the world, and not according to Christ. 9 For in Him dwells all the fullness of the Godhead bodily; 10 and you are complete in Him, who is the head of all principality and power
Sometimes we use poor examples from life to describe our lives. A jigsaw puzzle seems like a good example where in we see ourselves as incomplete persons going through life looking for our missing parts. In Christ, you are "complete." Your are NOTHING LIKE a jigsaw puzzle!
You might say, "I'm missing some things I need." You are only missing what you have not discovered. You have it, you just haven't seen it. If there is something needed, God will impart in connection with His purpose for your life.
The fullness of the Godhead dwells in Jesus AND you are complete in Him.
