“And this is my prayer: that your love may abound more and more in knowledge and depth of insight, so that you may be able to discern what is best and may be pure and blameless for the day of Christ,”
— Philippians 1:9-10
Abound means to exceed beyond what is normal. It is to have an overabundance that pours out of the storehouse. In this case, Paul means a Christian. He prayed that the pure love God gave to them would be so great it could not be contained in themselves, but would pour out on people who were around them so they would be blessed, too.
Paul also prayed the Christian’s’ pure agape love from God would abound so that they would have godly knowledge from their continual and growing relationship with God. God’s love won’t be evident and overflowing in a person’s life without a growing relationship with Him.
Along with knowledge, Paul prayed the Christians would have a “depth of insight.” He wanted them to have a profound understanding/insight/discernment of their situation through their intellect and by their senses. By this, they could size things up correctly and understand it rightly because of their growing relationship with God. That growing relationship with God brings growth in having His wisdom and knowledge so they can have His understanding/insight and act, speak, and think correctly.
By having a continual and growing relationship with God, a Christian can have overabundant pure, godly love, knowledge, and insight. With these three things, he/she can know what is best, may be pure, and not stumble into sin. All of these can only occur when we have a close relationship with God. They only come from God because only He is pure and sinless.
