God showed He could protect against all inadequacies and death. Israel saw His great works in Egypt. The Ethiopian eunuch was told that more than 500 people witnessed the resurrection of Jesus. Both asked for baptism, the opportunity to leave serving mammon and join to serve God.
Baptism is a commitment. That's why many people counted the cost before making the promise to serve God unconditionally, so that they would not be ridiculed for starting to build a tower and not being able to complete it:
Acts 5
13But none of the rest dared to associate with them; however, the people held them in high esteem.
Do you think that if the offer of following Christ was cheap it would then result in people being careful to count the cost? That's a simple questioning, analysis, of your cheap grace view.
When baptism led to drinking from the Rock, further revelation of God's ability to protect, Israel sinned in forgetting the great works God did:
Psalms 78King James Bible
11And forgat his works, and his wonders that he had shewed them.
Similarly, Ananias and Sapphira forgot the words of life that freed them from mammon. After baptism they forgot the words of life that showed God could protect even if they gave up all their possessions. They couldn't go back to mammon. People would ridicule them. So before they were found to be tardy, they pretended to give everything up.
Of course you haven't even been called, been told what the offer was, so how would you know, been witness to God's great works? You have to feel uncomfortable in the world, alienated, before you grope for God, seek Him.
Acts 17 KJV
26And hath made of one blood all nations of men for to dwell on all the face of the earth, and hath determined the times before appointed, and the bounds of their habitation;
27That they should seek the Lord, if haply they might feel after him, and find him, though he be not far from every one of us:
28For in him we live, and move, and have our being; as certain also of your own poets have said, For we are also his offspring.
