The Church was praying for the deliverance of Peter and God seemed to be silent for a while but suddenly he intervened just in time before Herod could execute his heinous plan. Let not your heart be troubled when the answer to your prayer appears to be delayed. The just-in-time God never shows up late.
As a man thinks in his heart so is he: you are the product of your thoughts. Unbelievers are not concerned about going to heaven so their affection is set on earthly things. They are worldly because the god of this world controls them. Believers should not be conformed to this world because although they are in the world, they are not of the world. Every believer should therefore seek to have the mind of Christ.
When God saved Israel from Egyptian bondage and captivity, He hedged them in with a cover of protection. However, every time they rejected God and worshipped strange gods, the hedge was broken and their enemies pursued and overpowered them. But whenever they repented and returned to the Lord, he always delivered them. That was a dangerous pattern which no believer should ever imitate. You should never take the grace of God for granted.
Joseph, in Potiphar's house, refused to commit immorality with his master's wife. Daniel, in Babylon did not defile himself with the portion of the king's food and drink. The Hebrew children declared their stand and walked worthy of God, even in a foreign country. The unchanging standard of God's word demands that we live right always and everywhere.
Since most deaths happen suddenly and in a moment, be sure that you walk circumspectly, not as fools, but as wise - Ephesians 5:15. It is only a few people, like one of the thieves on the cross that may have an opportunity to make their ways right with God, just before death. The majority of people die either accidentally or in their sleep, taken away without hand.
