steadfast

"Remaining steadfast may mean ... persevering until what we had hoped to achieve begins to come into view." (Ringma, Reflection 91)
It's an interesting thought that we should not necessarily wait for the fulfilment of what we hope for.  It is enough to begin to see it.  The fulfilment is always in the hands of God.  If we plan to stay until everything is complete, we risk taking full responsibility for it ourselves instead of leaving it to God's care.  God charges us with the task of planting seeds - that's all!  The rest of the work - growing the seed to harvest - is God's work, not mine or yours.  Sometimes God will grant the privilege for us to see the fulfilment, but I must not assume it or expect it.
This is the joy in 1 Corinthinan 15:35-58.  We can "be steadfast, immovable, always excelling in the work of the Lord, because we know that [whatever work we do] in the Lord our labour is not in vain."
