In the morning sow thy seed, and in the evening withhold not thine hand: for thou knowest not whether shall prosper, either this or that, or whether they both shall be alike good. Ecclesiasties 11:6

Telling others about God's loving plan for blessing all the families of the earth is pictured as sowing our seed. We have no way of knowing whether or not those to whom we witness will want to learn more, so we should be prompt to use every opportunity to share the good news and leave the results to the LORD. Matthew 24:14
