The Bible makes a statement which is difficult for human beings to follow. The Bible says, "For we walk by faith, not by sight" (II Corinthians 5:7). We all have a measure of faith, but we easily slide into that mode of wanting to see results immediately. When we walk by faith, we aren't looking with natural eyes, but with the eyes of the Spirit guided by the Word of the Lord.
During Paul's second missionary journey, after they had gone through the region of Galatia strengthening the churches, they now tried to walk by faith into new regions. They attempted to go into Asia but were forbidden by the Holy Ghost, and then the Spirit of God didn't allow them to go into Mysia (Acts 16:6-7). Paul had a vision that night of a man from Macedonia beckoning them to come over, so they went (Acts 16:9).
In a short while, they had been beaten and were in prison, but Paul and Silas were walking by faith, not by sight. Paul and Silas prayed out loud and sang praises to the Lord at midnight, and the Lord worked a miracle of deliverance.
The natural eyes would tell Paul and Silas that what they were doing wasn't working and they made a mistake; however, faith took over, and deliverance came, as well as salvation to the jailer's household (Acts 16:30-33).
The Bible tells us to preach the Gospel, and signs will follow. They may follow immediately or some time afterwards. As long as we continue to walk by faith, the Lord is going to bless and work (Mark 16:15-20). Let's keep walking by faith!
