Our forefathers were all under the cloud and that they all passed through the sea. They were all baptized into Moses in the cloud and in the sea. They all ate same spiritual food ... Nevertheless God was not pleased with most of them. 1 Corinthians 10:1-5
Why was God not pleased? The next verses tell us that some were idolaters, some committed sexual immorality, some tested the Lord and some grumbled. Despite the fact that the Israelites had gone through some wonderful spiritual experiences most were still not right with God. We can go through the outward appearances of baptism and have other spiritual experiences but that in itself does not please God, if our heart attitude is not right.
Jesus called the Pharisees "whitewashed tombs" because they appeared to people as righteous since they searched the Scriptures, prayed regularly, tithed and fasted but on the inside their hearts were not right with God.
In verses 6 & 11 of 1 Corinthians 10 we are told that the things that happened to the Israelites were recorded as warnings and examples to us. We can't expect God to be pleased with us just because we have been baptised or because we are members of the church.
So what does please God? As Micah 6:8 brings out God is pleased when we act justly, love mercy and walk humbly with our God because we can only do these things when our heart attitude is right.
