The eventual welfare of the Ephesian converts drove Paul to prayer. The unusual prayer style may have been for emphasis. The old practice was to stand for prayer. B. Paul knew the source for all evangelistic success. The power to grow in the gospel comes from God through the work of the Holy Spirit.
Believers become new from the inside out.
Goals and expectations shift. All the power to accomplish changes comes through this internal development God undertakes in believers. D. Believers become sturdy and secure when the Spirit of Christ fills them. Remember the living temple image of the New Testament. Ye also, as lively stones , are built up a spiritual house , an holy priesthood, to offer up spiritual sacrifices, acceptable to God by Jesus Christ.
