When He had finished speaking, He said to Simon, "Now go out where it is deeper, and let down your nets to catch some fish" (Luke 5:4).
Jesus gave the above instruction to His despondent disciples. They had been fishing all night, without success. Despite physical fatigue, disappointment and the fact that they knew Jesus was not a fisherman, they obeyed Him.
Christ gave us His Spirit in our hearts to make us holy. He calls on His followers to venture bravely into deeper spiritual waters, and not flounder in shallow muddy water. Too many of His children waste their spiritual strength on the surface, without ever reaching for the abundant depths.
Like the early church of Laodicea, we are neither nor cold. Because we are lukewarm, we cannot reach, or make use of, the full depths of the life that Christ has in mind for us through His Spirit.
If this is happening in your spiritual life at the moment, make a decisive and honest effort to do something about it. Be as serious in your approach to your spiritual growth as the situation deserves. Ask the Spirit to let you take to heart the challenge in John 15:4-5: "Remain in Me ... you cannot be fruitful unless you remain in Me." Don't settle for second best. If His Spirit leads you to the full depths of your relationship with your Savior, you will be rich and strong, surging forward to where Christ wants to take you and use you.
