John 20.26-29 cont.
26 And after eight days His disciples were inside, and Thomas was with them. The doors had been shut, yet Jesus came and stood in the middle and said: “Peace to you”.
27 Then He said (says) to Thomas: “Bring your finger here and see My hands, and bring your hand and put it into My side. Be not unbelieving, but believe.
28 Thomas replied: “My Lord and my God.”
29 Jesus said (says) to him: Have you believed, because you have seen Me? How happy are the ones who do not see and yet they have believed.
It is often said that it is all right to have doubts. However, it might be better to say that all of us are affected by doubts at some time or another. In that sense we are all the same, doubts do attack us. Sometimes the attack is from the devil, but at other times the doubts that we have are generated from within our own lack of faith and understanding.
There is no suggestion by Jesus that the doubts that Thomas had were from the devil, instead Jesus implies that they were from within Thomas. Jesus told Thomas not to be unbelieving, but to believe. Therefore, the consequence of his lack of faith in the testimony of the other disciples was his doing, and his alone.
We must always be aware that any doubts we have are most likely to come from within ourselves, which means that they are not necessarily an attack from the devil.
How are we to deal with doubts and unbelief?
The simple answer is to obey the command of Jesus, which He gave to Thomas:
Be not unbelieving, but believe.
This is a command from Jesus, and His commands are good for us and bring us into a fuller measure of His blessing.
We all need to face each doubt with these words from Jesus, so that we smash every doubt, and every ounce of unbelief.
King David had an excellent way of dealing with doubt, depression, dejection, and despair, and it was to force himself to remember what God had already done for him:
 Praise the LORD, I tell myself, and never forget the good things He does for me.
 He forgives all my sins and heals all my diseases.
 He ransoms me from death and surrounds me with love and tender mercies.
 He fills my life with good things. My youth is renewed like the eagle’s! – Psalm 103.2-5.
God’s word tells us:
When you ask Him, be sure that you really expect Him to answer, for a doubtful mind is as unsettled as a wave of the sea that is driven and tossed by the wind – James 1.5 (NLT).
Let us all renew our determination to always believe what God says to us.
