Our great tendency in this age is to increase our speed, to run faster, even in the Christian life. In the process our walk with God stays shallow, and our tank runs low on fumes. Intimacy offers a full tank of fuel that can only be found by pulling up closer to God, which requires taking necessary time and going to the effort to make that happen.
Good intentions and earnest effort are not enough. Only Jesus can make an otherwise futile life productive.
