One beautiful characteristic of life in Christ is its fullness. Jesus Christ is Himself "the fullness of him that filleth all in all" (Ephesians 1:23), and He does everything to the full! When He fed the multitude, there were twelve baskets left over (John 6:13); when He brought in the miraculous catch of fishes, the nets were so full that they broke, and the boats so full they began to sink (Luke 5:6-7).
First of all, He gives fullness of grace. "And of his fullness have all we received, and grace for grace" (John 1:16). Then comes fullness of joy and peace: "These things have I spoken unto you, that my joy might remain in you, and that your joy might be full" (John 15:11). "Now the God of hope fill you with all joy and peace in believing" (Romans 15:13).
It is then possible--in fact, we are commanded--to be "filled with the Spirit . . . making melody in your heart to the Lord" (Ephesians 5:18-19). Not only does the Holy Spirit indwell us, but so do the Father and the Son, by the Spirit. Jesus said: "If a man love me, he will keep my words: and my Father will love him, and we will come unto him, and make our abode with him" (John 14:23). In this way, the triune God indwells us, and thereby we "know the love of Christ, which passeth knowledge, that |we| might be filled with all the fullness of God" (Ephesians 3:19).
All the fullness of God! In Jesus Christ "dwelleth all the fullness of the Godhead bodily. And ye are complete in him" (Colossians 2:9-10), "for it pleased the Father that in him should all fullness dwell" (Colossians 1:19). With the resources of such fullness of blessing available to us, we should be constantly growing "unto the measure of the stature of the fullness of Christ" (Ephesians 4:13). HMM
