While we cherish the blessing of the early rain, we must not, on the other hand, lose sight of the fact that without the latter rain, to fill out the ears and ripen the grain, the harvest will not be ready for the sickle, and the labor of the sower will have been in vain. Divine grace is needed at the beginning, divine grace at every step of advance, and divine grace alone can complete the work....
Do not rest satisfied that in the ordinary course of the season, rain will fall. Ask for it.... We must seek His favors with the whole heart if the showers of grace are to come to us. We should improve every opportunity of placing ourselves in the channel of blessing. Christ has said, “Where two or three are gathered together in my name, there am I in the midst.” Matthew 18:20. The convocations of the church, as in camp meetings, the assemblies of the home church, and all occasions where there is personal labor for souls, are God’s appointed opportunities for giving the early and the latter rain....
At every meeting we attend our prayers should ascend that at this very time, God will impart warmth and moisture to our souls. As we seek God for the Holy Spirit, it will work in us meekness, humbleness of mind, a conscious dependence upon God for the perfecting latter rain. If we pray for the blessing in faith, we shall receive it as God has promised.
The first neglect of prayer and Bible study makes easier the second neglect. The first resistance to the Spirit’s pleading prepares the way for the second resistance. Thus the heart is hardened, and the conscience seared. Pr 181-182
"Ask ye of the Lord rain in the time of the latter rain; so the Lord shall make bright clouds, and give them showers of rain, to every one grass in the field." Zechariah 10:1 (King James Version)
